Description
The M29W640G is a 64 Mbit (8Mb x8 or 4Mb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Program and Erase commands are written to the Command Interface of the memory. An on-chip Program/Erase Controller simplifies the process of programming or erasing the memory by taking care of all of the special operations that are required to update the memory contents. The end of a program or erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards. The M29W640GH and M29W640GL memory array is organized into 128 uniform Blocks of 64 Kbytes each (or 32 Kwords each). The M29W640GT and M29W640GB feature an asymmetric block architecture. The devices have an array of 135 blocks, divided into 8 Parameter Blocks of 8 Kbytes each (or 4 Kwords each), and 127 Main Blocks of 64 Kbytes each (or 32 Kwords each). The M29W640GT has the Parameter Blocks at the top of the memory address space while the M29W640GB locates the Parameter Blocks starting from the bottom. Blocks are protected by groups to prevent accidental Program or Erase commands from modifying the memory.

Table 3, describes the protection granularity on the M29W640GH and M29W640GL. Table 4, and Table 5. describe the protection granularity on the M29W640GT and M29W640GB.
The M29W640G support Asynchronous Random Read and Page Read from all blocks of the memory array. Chip Enable, Output Enable and Write Enable signals control the bus operation of the memory. They allow simple connection to most microprocessors, often without additional logic. The VPP/WP signal is used to enable faster programming of the device. Protection from Program/Erase operation can be obtained by holding VPP/WP to VSS:

On the M29W640GH and M29W640GL, the last and the first block is protected, respectively. On the M29W640GT and M29W640GB, the first two and the last two boot blocks are protected.
The devices feature a full set of Fast Program commands to improve the programming throughput:

2 Byte Program: it is not necessary to raise VPP/WP to 12V before issuing this command 2 Words/4 Bytes Program: it is not necessary to raise VPP/WP to 12V before issuing this command. 4 Words/8 Bytes Program: VPP/WP must be raised to 12V before issuing this command. Write to Buffer and Program, allowing to program in one shot a buffer of 16 words/32 bytes.

Description
M29W640GH, M29W640GL, M29W640GT, M29W640GB The M29W640G has an extra block, the Extended Block, of 128 words in x16 mode or of 256 bytes in x8 mode that can be accessed using a dedicated command. The Extended Block can be protected and so is useful for storing security information. However the protection is not reversible, once protected the protection cannot be undone. The M29W640GT, M29W640GB, M29W640GH and M29W640GL, are offered in TSOP48 (12x 20mm), TSOP56 (14x 20mm), TFBGA48 (6 x8mm, 0.8mm pitch), and TBGA64 (10x 13mm, 1mm pitch) packages. In order to meet environmental requirements, Numonyx offers the M29W640GH, M29W640GL, M29W640GT and M29W640GB in ECOPACK(R) packages. ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. The memory is delivered with all the bits erased (set to 1). Figure 1. Logic diagram

Signal descriptions
See Figure 1: Logic diagram, and Table 2: Signal names, for a brief overview of the signals connected to the device.
2.1
Address Inputs (A0-A21)
The Address Inputs select the cells in the memory array to access during Bus Read operations. During Bus Write operations they control the commands sent to the Command Interface of the Program/Erase Controller.
2.2
Data Inputs/Outputs (DQ0-DQ7)
The Data I/O outputs the data stored at the selected address during a Bus Read operation. During Bus Write operations they represent the commands sent to the Command Interface of the Program/Erase Controller.
2.3
Data Inputs/Outputs (DQ8-DQ14)
The Data I/O outputs the data stored at the selected address during a Bus Read operation when BYTE is High, VIH. When BYTE is Low, VIL, these pins are not used and are high impedance. During Bus Write operations the Command Register does not use these bits. When reading the Status Register these bits should be ignored.
2.4
Data Input/Output or Address Input (DQ15A-1)
When BYTE is High, VIH, this pin behaves as a Data Input/Output pin (as DQ8-DQ14). When BYTE is Low, VIL, this pin behaves as an address pin; DQ15A-1 Low will select the LSB of the addressed word, DQ15A-1 High will select the MSB. Throughout the text consider references to the Data Input/Output to include this pin when BYTE is High and references to the Address Inputs to include this pin when BYTE is Low except when stated explicitly otherwise.
2.5
Chip Enable (E)
The Chip Enable, E, activates the memory, allowing Bus Read and Bus Write operations to be performed. When Chip Enable is High, VIH, all other pins are ignored.
2.6
Output Enable (G)
The Output Enable, G, controls the Bus Read operation of the memory.

Signal descriptions
2.7
Write Enable (W)
The Write Enable, W, controls the Bus Write operation of the memory's Command Interface.
2.8
VPP/Write Protect (VPP/WP)
The VPP/Write Protect pin provides two functions. The VPP function allows the memory to use an external high voltage power supply to reduce the time required for Unlock Bypass Program operations. The Write Protect performs hardware protection:

It protects the first and last block on M29W640GH and M29W640GL devices. It protects the first two and the last two boot blocks on M29W640GT and M29W640GB devices.
The VPP/Write Protect pin may be left floating or unconnected (see Table 17: DC characteristics). When VPP/Write Protect is Low, VIL, the two outermost (M29W640GH and M29W640GL) or four outermost blocks (M29W640GT and M29W640GB) are protected. Program and Erase operations in this block are ignored while VPP/Write Protect is Low, even when RP is at VID. When VPP/Write Protect is High, VIH, the memory reverts to the previous protection status of the outermost blocks. Program and Erase operations can now modify the data in the outermost blocks unless the block is protected using Block Protection. Applying 12V to the VPP/WP pin will temporarily unprotect any block previously protected (including the outermost blocks) using a High Voltage Block Protection technique (InSystem or Programmer technique). See Table 6: Hardware Protection for details. When VPP/Write Protect is raised to VPP the memory automatically enters the Unlock Bypass mode. When VPP/Write Protect returns to VIH or VIL normal operation resumes. During Unlock Bypass Program operations the memory draws IPP from the pin to supply the programming circuits. See the description of the Unlock Bypass command in the Command Interface section. The transitions from VIH to VPP and from VPP to VIH must be slower than tVHVPP, see Figure 18: Accelerated Program Timing waveforms. Never raise VPP/Write Protect to VPP from any mode except Read mode, otherwise the memory may be left in an indeterminate state. A 0.1F capacitor should be connected between the VPP/Write Protect pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Unlock Bypass Program, IPP. Table 6.

2.9
Reset/Block Temporary Unprotect (RP)
The Reset/Block Temporary Unprotect pin can be used to apply a Hardware Reset to the memory or to temporarily unprotect all Blocks that have been protected. Note that if VPP/WP is at VIL, then the two or four outermost blocks will remain protected even if RP is at VID. A Hardware Reset is achieved by holding Reset/Block Temporary Unprotect Low, VIL, for at least tPLPX. After Reset/Block Temporary Unprotect goes High, VIH, the memory will be ready for Bus Read and Bus Write operations after tPHEL or tRHEL, whichever occurs last. See the Ready/Busy Output section, Table 20: Reset/Block Temporary Unprotect ac Characteristics and Figure 17: Reset/Block Temporary Unprotect ac waveforms, for more details. Holding RP at VID will temporarily unprotect the protected Blocks in the memory. Program and Erase operations on all blocks will be possible. The transition from VIH to VID must be slower than tPHPHH.
2.10
Ready/Busy Output (RB)
The Ready/Busy pin is an open-drain output that can be used to identify when the device is performing a Program or Erase operation. During Program or Erase operations Ready/Busy is Low, VOL. Ready/Busy is high-impedance during Read mode, Auto Select mode and Erase Suspend mode. After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy becomes high-impedance. See Table 20: Reset/Block Temporary Unprotect ac Characteristics and Figure 17: Reset/Block Temporary Unprotect ac waveforms, for more details. The use of an open-drain output allows the Ready/Busy pins from several memories to be connected to a single pull-up resistor. A Low will then indicate that one, or more, of the memories is busy.
2.11
Byte/Word Organization Select (BYTE)
The Byte/Word Organization Select pin is used to switch between the x8 and x16 Bus modes of the memory. When Byte/Word Organization Select is Low, VIL, the memory is in x8 mode, when it is High, VIH, the memory is in x16 mode.

2.12
VCC Supply Voltage
VCC provides the power supply for all operations (Read, Program and Erase). The Command Interface is disabled when the VCC Supply Voltage is less than the Lockout Voltage, VLKO. This prevents Bus Write operations from accidentally damaging the data during power up, power down and power surges. If the Program/Erase Controller is programming or erasing during this time then the operation aborts and the memory contents being altered will be invalid. A 0.1F capacitor should be connected between the VCC Supply Voltage pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Program and Erase operations, ICC3.
2.13
VSS Ground
VSS is the reference for all voltage measurements. The device features two VSS pins which must be both connected to the system ground.

Bus operations
3
Bus operations
There are five standard bus operations that control the device. These are Bus Read, Bus Write, Output Disable, Standby and Automatic Standby. See Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, for a summary. Typically glitches of less than 5ns on Chip Enable or Write Enable are ignored by the memory and do not affect bus operations.
3.1
Bus Read
Bus Read operations read from the memory cells, or specific registers in the Command Interface. A valid Bus Read operation involves setting the desired address on the Address Inputs, applying a Low signal, VIL, to Chip Enable and Output Enable and keeping Write Enable High, VIH. The Data Inputs/Outputs will output the value, see Figure 13: Read Mode ac waveforms (8-bit mode), and Table 18: Read ac characteristics, for details of when the output becomes valid.
3.2
Bus Write
Bus Write operations write to the Command Interface. To speed up the read operation the memory array can be read in Page mode where data is internally read and stored in a page buffer. The Page has a size of 4 words and is addressed by the address inputs A0-A1. A valid Bus Write operation begins by setting the desired address on the Address Inputs. The Address Inputs are latched by the Command Interface on the falling edge of Chip Enable or Write Enable, whichever occurs last. The Data Inputs/Outputs are latched by the Command Interface on the rising edge of Chip Enable or Write Enable, whichever occurs first. Output Enable must remain High, VIH, during the whole Bus Write operation. See Figure 15: Write ac waveforms, Write Enable Controlled (8-bit mode), Figure 16: Write ac waveforms, Chip Enable Controlled (8-bit mode), and Table 19: Write ac characteristics and Table 19: Write ac characteristics, for details of the timing requirements.
3.3
Output Disable
The Data Inputs/Outputs are in the high impedance state when Output Enable is High, VIH.
3.4
Standby
When Chip Enable is High, VIH, the memory enters Standby mode and the Data Inputs/Outputs pins are placed in the high-impedance state. To reduce the Supply Current to the Standby Supply Current, ICC2, Chip Enable should be held within VCC 0.2V. For the Standby current level see Table 17: DC characteristics. During program or erase operations the memory will continue to use the Program/Erase Supply Current, ICC3, for Program or Erase operations until the operation completes.
19/90

M29W640GH, M29W640GL, M29W640GT, M29W640GB
3.5
Automatic Standby
If CMOS levels (VCC 0.2V) are used to drive the bus and the bus is inactive for 300ns or more the memory enters Automatic Standby where the internal Supply Current is reduced to the Standby Supply Current, ICC2. The Data Inputs/Outputs will still output data if a Bus Read operation is in progress.
3.6
Special Bus Operations
Additional bus operations can be performed to read the Electronic Signature and also to apply and remove Block Protection. These bus operations are intended for use by programming equipment and are not usually used in applications. They require VID to be applied to some pins.
3.6.1
Electronic Signature
The memory has two codes, the manufacturer code and the device code, that can be read to identify the memory. These codes can be read by applying the signals listed in Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, with A9 set to VID.
3.6.2
Block Protect and Chip Unprotect
Groups of blocks can be protected against accidental Program or Erase. The Protection Groups are shown in Appendix A: Block addresses Table 28 and Table 29. The whole chip can be unprotected to allow the data inside the blocks to be changed. The VPP/Write Protect pin can be used to protect the two outermost blocks on the M29W640GH and M29W640GL, and the four outermost blocks on the M29W640GT and M29W640GB. When VPP/Write Protect is at VIL the outermost blocks are protected and remain protected regardless of the Block Protection Status or the Reset/Block Temporary Unprotect pin status. Block Protect and Chip Unprotect operations are described in : Revision history.

Command Interface
All Bus Write operations to the memory are interpreted by the Command Interface. Commands consist of one or more sequential Bus Write operations. Failure to observe a valid sequence of Bus Write operations will result in the memory returning to Read mode. The long command sequences are imposed to maximize data security. The address used for the commands changes depending on whether the memory is in 16bit or 8-bit mode. See either Table 10, or Table 11, depending on the configuration that is being used, for a summary of the commands.
4.1
4.1.1
Standard commands
Read/Reset command
The Read/Reset command returns the memory to its Read mode. It also resets the errors in the Status Register. Either one or three Bus Write operations can be used to issue the Read/Reset command. The Read/Reset command can be issued, between Bus Write cycles before the start of a program or erase operation, to return the device to read mode. If the Read/Reset command is issued during the timeout of a Block Erase operation then the memory will take up to 10s to abort. During the abort period no valid data can be read from the memory. The Read/Reset command will not abort an Erase operation when issued while in Erase Suspend.
4.1.2
Auto Select command
The Auto Select command is used to read the Manufacturer Code, the Device Code, the Block Protection Status and the Extended Memory Block Verify Code. Three consecutive Bus Write operations are required to issue the Auto Select command. Once the Auto Select command is issued the memory remains in Auto Select mode until a Read/Reset command is issued. Read CFI Query and Read/Reset commands are accepted in Auto Select mode, all other commands are ignored. In Auto Select mode, the Manufacturer Code and the Device Code can be read by using a Bus Read operation with addresses and control signals set as shown in Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, except for A9 that is `Don't Care'. The Block Protection Status of each block can be read using a Bus Read operation with addresses and control signals set as shown in Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, except for A9 that is `Don't Care'. If the addressed block is protected then 01h is output on Data Inputs/Outputs DQ0-DQ7, otherwise 00h is output (in 8-bit mode). The protection status of the Extended Memory block, or Extended Memory Block Verify code, can be read using a Bus Read operation with addresses and control signals set as shown in Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, except for A9 that is `Don't Care'. If the Extended Block is "Factory Locked" then 80h is output on Data Input/Outputs DQ0-DQ7, otherwise 00h is output (8-bit mode).

4.1.3
Read CFI Query command
The Read CFI Query Command is used to read data from the Common Flash Interface (CFI) Memory Area. This command is valid when the device is in the Read Array mode, or when the device is in Autoselected mode. One Bus Write cycle is required to issue the Read CFI Query Command. Once the command is issued subsequent Bus Read operations read from the Common Flash Interface Memory Area. The Read/Reset command must be issued to return the device to the previous mode (the Read Array mode or Autoselected mode). A second Read/Reset command would be needed if the device is to be put in the Read Array mode from Autoselected mode. See Appendix B: Common Flash Interface (CFI), Tables 30, 31, 32, 33, 34 and 35 for details on the information contained in the Common Flash Interface (CFI) memory area.
4.1.4
Chip Erase command
The Chip Erase command can be used to erase the entire chip. Six Bus Write operations are required to issue the Chip Erase Command and start the Program/Erase Controller. If any blocks are protected then these are ignored and all the other blocks are erased. If all of the blocks are protected the Chip Erase operation appears to start but will terminate within about 100s, leaving the data unchanged. No error condition is given when protected blocks are ignored. During the erase operation the memory will ignore all commands, including the Erase Suspend command. It is not possible to issue any command to abort the operation. Typical chip erase times are given in Table 12: Program, Erase times and endurance cycles. All Bus Read operations during the Chip Erase operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. After the Chip Erase operation has completed the memory will return to the Read Mode, unless an error has occurred. When an error occurs the memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read Mode. The Chip Erase Command sets all of the bits in unprotected blocks of the memory to '1'. All previous data is lost. Refer to Figure 8: Chip/Block Erase waveforms (8-bit mode) for a description of Chip Erase ac waveforms.

Command Interface
4.1.5
Block Erase command
The Block Erase command can be used to erase a list of one or more blocks. Six Bus Write operations are required to select the first block in the list. Each additional block in the list can be selected by repeating the sixth Bus Write operation using the address of the additional block. The Block Erase operation starts the Program/Erase Controller about 50s after the last Bus Write operation. Once the Program/Erase Controller starts it is not possible to select any more blocks. Each additional block must therefore be selected within 50s of the last block. The 50s timer restarts when an additional block is selected. The Status Register can be read after the sixth Bus Write operation. See the Status Register section for details on how to identify if the Program/Erase Controller has started the Block Erase operation. If any selected blocks are protected then these are ignored and all the other selected blocks are erased. If all of the selected blocks are protected the Block Erase operation appears to start but will terminate within about 100s, leaving the data unchanged. No error condition is given when protected blocks are ignored. During the Block Erase operation the memory will ignore all commands except the Erase Suspend command. Typical block erase times are given in Table 12: Program, Erase times and endurance cycles. All Bus Read operations during the Block Erase operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. After the Block Erase operation has completed the memory will return to the Read Mode, unless an error has occurred. When an error occurs the memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode. The Block Erase Command sets all of the bits in the unprotected selected blocks to '1'. All previous data in the selected blocks is lost. Refer to Figure 8: Chip/Block Erase waveforms (8-bit mode) for a description of Block Erase ac waveforms.
4.1.6
Erase Suspend command
The Erase Suspend Command may be used to temporarily suspend a Block Erase operation and return the memory to Read mode. The command requires one Bus Write operation. The Program/Erase Controller will suspend within the Erase Suspend Latency time of the Erase Suspend Command being issued. Once the Program/Erase Controller has stopped the memory will be set to Read mode and the Erase will be suspended. If the Erase Suspend command is issued during the period when the memory is waiting for an additional block (before the Program/Erase Controller starts) then the Erase is suspended immediately and will start immediately when the Erase Resume Command is issued. It is not possible to select any further blocks to erase after the Erase Resume. During Erase Suspend it is possible to Read and Program cells in blocks that are not being erased; both Read and Program operations behave as normal on these blocks. If any attempt is made to program in a protected block or in the suspended block then the Program command is ignored and the data remains unchanged. The Status Register is not read and no error condition is given. Reading from blocks that are being erased will output the Status Register.
25/90
Command Interface
M29W640GH, M29W640GL, M29W640GT, M29W640GB
It is also possible to issue the Auto Select, Read CFI Query and Unlock Bypass commands during an Erase Suspend. The Read/Reset command must be issued to return the device to Read Array mode before the Resume command will be accepted.
4.1.7
Erase Resume command
The Erase Resume command must be used to restart the Program/Erase Controller after an Erase Suspend. The device must be in Read Array mode before the Resume command will be accepted. An erase can be suspended and resumed more than once.
4.1.8
Program Suspend command
The Program Suspend command allows the system to interrupt a program operation so that data can be read from any block. When the Program Suspend command is issued during a program operation, the device suspends the program operation within the Program Suspend Latency time (see Table 12: Program, Erase times and endurance cycles for value) and updates the Status Register bits. After the program operation has been suspended, the system can read array data from any address. However, data read from Program-Suspended addresses is not valid. The Program Suspend command may also be issued during a program operation while an erase is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program Suspend. If a read is needed from the Extended Block area (One-time Program area), the user must use the proper command sequences to enter and exit this region. The system may also issue the Auto Select command sequence when the device is in the Program Suspend mode. The system can read as many Auto Select codes as required. When the device exits the Auto Select mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See Auto Select command sequence for more information.
4.1.9
Program Resume command
After the Program Resume command is issued, the device reverts to programming. The controller can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See Write Operation Status for more information. The system must write the Program Resume command, to exit the Program Suspend mode and to continue the programming operation. Further issuing of the Resume command is ignored. Another Program Suspend command can be written after the device has resumed programming.

Command Interface
4.1.10
Program command
The Program command can be used to program a value to one address in the memory array at a time. The command requires four Bus Write operations, the final write operation latches the address and data, and starts the Program/Erase Controller. Programming can be suspended and then resumed by issuing a Program Suspend command and a Program Resume command, respectively (see Section 4.1.8: Program Suspend command and Section 4.1.9: Program Resume command). If the address falls in a protected block then the Program command is ignored, the data remains unchanged. The Status Register is never read and no error condition is given. During the program operation the memory will ignore all commands. It is not possible to issue any command to abort or pause the operation. Typical program times are given in Table 12: Program, Erase times and endurance cycles. Bus Read operations during the program operation will output the Status Register on the Data Inputs/Outputs. See the section on the Status Register for more details. After the program operation has completed the memory will return to the Read mode, unless an error has occurred. When an error occurs the memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode. Note that the Program command cannot change a bit set at '0' back to '1'. One of the Erase Commands must be used to set all the bits in a block or in the whole memory from '0' to '1'. Refer to Figure 6: Write Enable controlled Program waveforms (8-bit mode) and Figure 7: Chip Enable controlled Program waveforms (8-bit mode) for a description of Program ac waveforms.

Fast Program commands
There are five Fast Program commands available to improve the programming throughput, by writing several adjacent words or bytes in parallel:

Quadruple and Octuple Byte Program, available for x8 operations Double and Quadruple Word Program, available for x16 operations Write to Buffer and Program
Fast Program commands can be suspended and then resumed by issuing a Program Suspend command and a Program Resume command, respectively (see Section 4.1.8: Program Suspend command and Section 4.1.9: Program Resume command).
4.2.1
Double Byte Program command
The Double Byte Program command is used to write a page of two adjacent bytes in parallel. The two bytes must differ only in DQ15A-1. Three bus write cycles are necessary to issue the Double Byte Program command. 1. 2. 3. The first bus cycle sets up the Double Byte Program Command. The second bus cycle latches the Address and the Data of the first byte to be written. The third bus cycle latches the Address and the Data of the second byte to be written.
Note:
It is not necessary to raise VPP/WP to 12V before issuing this command.
4.2.2
Quadruple Byte Program command
The Quadruple Byte Program command is used to write a page of four adjacent bytes in parallel. The four bytes must differ only for addresses A0, DQ15A-1. Five bus write cycles are necessary to issue the Quadruple Byte Program command: 1. 2. 3. 4. 5. The first bus cycle sets up the Quadruple Byte Program Command. The second bus cycle latches the Address and the Data of the first byte to be written. The third bus cycle latches the Address and the Data of the second byte to be written. The fourth bus cycle latches the Address and the Data of the third byte to be written. The fifth bus cycle latches the Address and the Data of the fourth byte to be written and starts the Program/Erase Controller.
Note:
It is not necessary to raise VPP/WP to 12V before issuing this command.

Command Interface
4.2.3
Octuple Byte Program command
This is used to write eight adjacent bytes, in x8 mode, simultaneously. The addresses of the eight bytes must differ only in A1, A0 and DQ15A-1. 12V must be applied to the VPP/Write Protect pin, VPP/WP, prior to issuing an Octuple Byte Program command. Care must be taken because applying a 12V voltage to the VPP/WP pin will temporarily unprotect any protected block. Nine bus write cycles are necessary to issue the command: 1. 2. 3. 4. 5. 6. 7. 8. 9. The first bus cycle sets up the command. The second bus cycle latches the Address and the Data of the first byte to be written. The third bus cycle latches the Address and the Data of the second byte to be written. The fourth bus cycle latches the Address and the Data of the third byte to be written. The fifth bus cycle latches the Address and the Data of the fourth byte to be written. The sixth bus cycle latches the Address and the Data of the fifth byte to be written. The seventh bus cycle latches the Address and the Data of the sixth byte to be written. The eighth bus cycle latches the Address and the Data of the seventh byte to be written. The ninth bus cycle latches the Address and the Data of the eighth byte to be written and starts the Program/Erase Controller.
4.2.4
Double Word Program command
The Double Word Program command is used to write a page of two adjacent words in parallel. The two words must differ only for the address A0. Three bus write cycles are necessary to issue the Double Word Program command.

The first bus cycle sets up the Double Word Program Command. The second bus cycle latches the Address and the Data of the first word to be written. The third bus cycle latches the Address and the Data of the second word to be written and starts the Program/Erase Controller.
After the program operation has completed the memory will return to the Read mode, unless an error has occurred. When an error occurs Bus Read operations will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode. Note that the Fast Program commands cannot change a bit set at '0' back to '1'. One of the Erase Commands must be used to set all the bits in a block or in the whole memory from '0' to '1'. Typical Program times are given in Table 12: Program, Erase times and endurance cycles. Note: It is not necessary to raise VPP/WP to 12V before issuing this command.

4.2.5
Quadruple Word Program command
This is used to write a page of four adjacent words (or 8 adjacent bytes), in x16 mode, simultaneously. The addresses of the four words must differ only in A1 and A0. 12V must be applied to the VPP/Write Protect pin, VPP/WP, prior to issuing a Quadruple Byte Program command. Care must be taken because applying a 12V voltage to the VPP/WP pin will temporarily unprotect any protected block. Five bus write cycles are necessary to issue the command:

The first bus cycle sets up the command. The second bus cycle latches the Address and the Data of the first word to be written. The third bus cycle latches the Address and the Data of the second word to be written. The fourth bus cycle latches the Address and the Data of the third word to be written. The fifth bus cycle latches the Address and the Data of the fourth word to be written and starts the Program/Erase Controller.
4.2.6
Unlock Bypass command
The Unlock Bypass command is used in conjunction with the Unlock Bypass Program command to program the memory faster than with the standard program commands. When the cycle time to the device is long, considerable time saving can be made by using these commands. Three Bus Write operations are required to issue the Unlock Bypass command. Once the Unlock Bypass command has been issued the memory will only accept the Unlock Bypass Program command and the Unlock Bypass Reset command. The memory can be read as if in Read mode. When VPP is applied to the VPP/Write Protect pin the memory automatically enters the Unlock Bypass mode and the Unlock Bypass Program command can be issued immediately.
4.2.7
Unlock Bypass Program command
The Unlock Bypass command is used in conjunction with the Unlock Bypass Program command to program the memory. When the cycle time to the device is long, considerable time saving can be made by using these commands. Three Bus Write operations are required to issue the Unlock Bypass command. Once the Unlock Bypass command has been issued the memory will only accept the Unlock Bypass Program command and the Unlock Bypass Reset command. The memory can be read as if in Read mode. The memory offers accelerated program operations through the VPP/Write Protect pin. When the system asserts VPP on the VPP/Write Protect pin, the memory automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The memory uses the higher voltage on the VPP/Write Protect pin, to accelerate the Unlock Bypass Program operation. Never raise VPP/Write Protect to VPP from any mode except Read mode, otherwise the memory may be left in an indeterminate state.

4.2.8
Unlock Bypass Reset command
The Unlock Bypass Reset command can be used to return to Read/Reset mode from Unlock Bypass Mode. Two Bus Write operations are required to issue the Unlock Bypass Reset command. Read/Reset command does not exit from Unlock Bypass Mode.
4.2.9
Write to Buffer and Program command
The Write to Buffer and Program command makes use of the device's 32-byte Write Buffer to speed up programming. 16 words/32 bytes can be loaded into the Write Buffer. Each Write Buffer has the same A4-A22 addresses.The Write to Buffer and Program command dramatically reduces system programming time compared to the standard non-buffered Program command. When issuing a Write to Buffer and Program command, the VPP/WP pin can be either held High, VIH or raised to VPPH. See Table 12 for details on typical Write to Buffer and Program times in both cases. Five successive steps are required to issue the Write to Buffer and Program command: 1. 2. 3. The Write to Buffer and Program command starts with two unlock cycles. The third Bus Write cycle sets up the Write to Buffer and Program command. The setup code can be addressed to any location within the targeted block. The fourth Bus Write cycle sets up the number of words to be programmed. Value n is written to the same block address, where n+1 is the number of words to be programmed. n+1 must not exceed the size of the Write Buffer or the operation will abort. The fifth cycle loads the first address and data to be programmed. Use n Bus Write cycles to load the address and data for each word into the Write Buffer. Addresses must lie within the range from the start address+1 to the start address + n-1. Optimum performance is obtained when the start address corresponds to a 64 byte boundary. If the start address is not aligned to a 64 byte boundary, the total programming time is doubled.
4. 5.
All the addresses used in the Write to Buffer and Program operation must lie within the same page. If an address is written several times during a Write to Buffer and Program operation, the address/data counter will be decremented at each data load operation and the data will be programmed to the last word loaded into the Buffer. Invalid address combinations or failing to follow the correct sequence of Bus Write cycles will abort the Write to Buffer and Program. The Status Register bits DQ1, DQ5, DQ6, DQ7 can be used to monitor the device status during a Write to Buffer and Program operation. It is possible to detect Program operation fails when changing programmed data from `0' to `1', that is when reprogramming data in a portion of memory already programmed. The resulting data will be the logical OR between the previous value and the current value. To program the content of the Write Buffer, this command must be followed by a Write to Buffer and Program Confirm command. A Write to Buffer and Program Abort and Reset command must be issued to abort the Write to Buffer and Program operation and reset the device in Read mode.
31/90
Command Interface
M29W640GH, M29W640GL, M29W640GT, M29W640GB
The Write Buffer Programming Sequence can be aborted in the following ways:

Load a value that is greater than the page buffer size during the Number of Locations to Program step. Write to an address in a block different than the one specified during the Write-BufferLoad command. Write an Address/Data pair to a different write-buffer-page than the one selected by the Starting Address during the write buffer data loading stage of the operation. Write data other than the Confirm Command after the specified number of data load cycles.
The abort condition is indicated by DQ1 = 1, DQ7 = DATA# (for the last address location loaded), DQ6 = toggle, and DQ5=0. A Write-to-Buffer-Abort Reset command sequence must be written to reset the device for the next operation. Note that the full 3-cycle Write-toBuffer-Abort Reset command sequence is required when using Write-Buffer-Programming features in Unlock Bypass mode. See Appendix E: Flowchart, Figure 29: Write to Buffer and Program flowchart and pseudo code, for a suggested flowchart on using the Write to Buffer and Program command.
4.2.10
Write to Buffer and Program Confirm command
The Write to Buffer and Program Confirm command is used to confirm a Write to Buffer and Program command and to program the n+1 words loaded in the Write Buffer by this command.
4.2.11
Write to Buffer and Program Abort and Reset command
The Write to Buffer and Program Abort and Reset command is used to reset the device after a Write to Buffer and Program command has been aborted.
4.3
4.3.1
Block Protection commands
Enter Extended Block command
The device has an extra 256 byte block (Extended Block) that can only be accessed using the Enter Extended Block command. Three Bus write cycles are required to issue the Extended Block command. Once the command has been issued the device enters Extended Block mode where all Bus Read or Write operations to the Boot Block addresses access the Extended Block. The Extended Block (with the same address as the Boot Blocks) cannot be erased, and can be treated as one-time programmable (OTP) memory. In Extended Block mode the Boot Blocks are not accessible. To exit from the Extended Block mode the Exit Extended Block command must be issued. The Extended Block can be protected, however once protected the protection cannot be undone.
4.3.2
Exit Extended Block command
The Exit Extended Block command is used to exit from the Extended Block mode and return the device to Read mode. Four Bus Write operations are required to issue the command.

Status Register
Bus Read operations from any address always read the Status Register during Program and Erase operations. It is also read during Erase Suspend when an address within a block being erased is accessed. The bits in the Status Register are summarized in Table 13: Status Register bits.
5.1
Data Polling Bit (DQ7)
The Data Polling Bit can be used to identify whether the Program/Erase Controller has successfully completed its operation or if it has responded to an Erase Suspend. The Data Polling Bit is output on DQ7 when the Status Register is read. During Program operations the Data Polling Bit outputs the complement of the bit being programmed to DQ7. After successful completion of the Program operation the memory returns to Read mode and Bus Read operations from the address just programmed output DQ7, not its complement. During Erase operations the Data Polling Bit outputs '0', the complement of the erased state of DQ7. After successful completion of the Erase operation the memory returns to Read Mode. In Erase Suspend mode the Data Polling Bit will output a '1' during a Bus Read operation within a block being erased. The Data Polling Bit will change from a '0' to a '1' when the Program/Erase Controller has suspended the Erase operation. Figure 9: Data polling flowchart, gives an example of how to use the Data Polling Bit. A Valid Address is the address being programmed or an address within the block being erased. Table 20: Reset/Block Temporary Unprotect ac Characteristics gives a description of the data polling operation and timings.
5.2
Toggle Bit (DQ6)
The Toggle Bit can be used to identify whether the Program/Erase Controller has successfully completed its operation or if it has responded to an Erase Suspend. The Toggle Bit is output on DQ6 when the Status Register is read. During Program and Erase operations the Toggle Bit changes from '0' to '1' to '0', etc., with successive Bus Read operations at any address. After successful completion of the operation the memory returns to Read mode. During Erase Suspend mode the Toggle Bit will output when addressing a cell within a block being erased. The Toggle Bit will stop toggling when the Program/Erase Controller has suspended the Erase operation. Figure 10: Data toggle flowchart, gives an example of how to use the Data Toggle Bit. Figure 20: Toggle/alternative Toggle bit polling ac waveforms (8-bit mode) gives a description of the data polling operation and timings.

Status Register
5.3
Error Bit (DQ5)
The Error Bit can be used to identify errors detected by the Program/Erase Controller. The Error Bit is set to '1' when a Program, Block Erase or Chip Erase operation fails to write the correct data to the memory. If the Error Bit is set a Read/Reset command must be issued before other commands are issued. The Error bit is output on DQ5 when the Status Register is read. Note that the Program command cannot change a bit set to '0' back to '1' and attempting to do so will set DQ5 to `1'. A Bus Read operation to that address will show the bit is still `0'. One of the Erase commands must be used to set all the bits in a block or in the whole memory from '0' to '1'.
5.4
Erase Timer Bit (DQ3)
The Erase Timer Bit can be used to identify the start of Program/Erase Controller operation during a Block Erase command. Once the Program/Erase Controller starts erasing the Erase Timer Bit is set to '1'. Before the Program/Erase Controller starts the Erase Timer Bit is set to '0' and additional blocks to be erased may be written to the Command Interface. The Erase Timer Bit is output on DQ3 when the Status Register is read.
5.5
Alternative Toggle Bit (DQ2)
The Alternative Toggle Bit can be used to monitor the Program/Erase controller during Erase operations. The Alternative Toggle Bit is output on DQ2 when the Status Register is read. During Chip Erase and Block Erase operations the Toggle Bit changes from '0' to '1' to '0', etc., with successive Bus Read operations from addresses within the blocks being erased. A protected block is treated the same as a block not being erased. Once the operation completes the memory returns to Read mode. During Erase Suspend the Alternative Toggle Bit changes from '0' to '1' to '0', etc. with successive Bus Read operations from addresses within the blocks being erased. Bus Read operations to addresses within blocks not being erased will output the memory cell data as if in Read mode. After an Erase operation that causes the Error Bit to be set the Alternative Toggle Bit can be used to identify which block or blocks have caused the error. The Alternative Toggle Bit changes from '0' to '1' to '0', etc. with successive Bus Read Operations from addresses within blocks that have not erased correctly. The Alternative Toggle Bit does not change if the addressed block has erased correctly. Figure 20: Toggle/alternative Toggle bit polling ac waveforms (8-bit mode) gives a description of the data polling operation and timings.
5.6
Write to Buffer and Program Abort Bit (DQ1)
The Write to Buffer and Program Abort bit, DQ1, is set to `1' when a Write to Buffer and Program operation aborts. Otherwise, DQ1 bit is set to `0'. The Write to Buffer and Program Abort and Reset command must be issued to return the device to Read mode (see Write to Buffer and Program in COMMANDS section).

Appendix B
Common Flash Interface (CFI)
The Common Flash Interface is a JEDEC approved, standardized data structure that can be read from the Flash memory device. It allows a system software to query the device to determine various electrical and timing parameters, density information and functions supported by the memory. The system can interface easily with the device, enabling the software to upgrade itself when necessary. When the CFI Query Command is issued the device enters CFI Query mode and the data structure is read from the memory. Tables 30, 31, 32, 33, 34, and 35, show the addresses used to retrieve the data. The CFI data structure also contains a security area where a 64 bit unique security number is written (see Table 35: Security code area). This area can be accessed only in Read mode by the final user. It is impossible to change the security number after it has been written by Numonyx. Table 30.

Extended Memory Block
Appendix C
Extended Memory Block
The M29W640G has an extra block, the Extended Block, that can be accessed using a dedicated command. This Extended Block is 128 words in x16 mode and 256 bytes in x8 mode. It is used as a security block to provide a permanent security identification number) or to store additional information. The Extended Block is either Factory Locked or Customer Lockable, its status is indicated by bit DQ7. This bit is permanently set to either `1' or `0' at the factory and cannot be changed. When set to `1', it indicates that the device is factory locked and the Extended Block is protected. When set to `0', it indicates that the device is customer lockable and the Extended Block is unprotected. Bit DQ7 being permanently locked to either `1' or `0' is another security feature which ensures that a customer lockable device cannot be used instead of a factory locked one. Bit DQ7 is the most significant bit in the Extended Block Verify Code and a specific procedure must be followed to read it. See "Extended Memory Block Verify Code" in Table 7: Bus Operations, BYTE = VIL and Table 8: Bus Operations, BYTE = VIH, for details of how to read bit DQ7. The Extended Block can only be accessed when the device is in Extended Block mode. For details of how the Extended Block mode is entered and exited, refer to the Section 4.3.1: Enter Extended Block command and Section 4.3.2: Exit Extended Block command, and to Table 10 and Table 11: Commands, 8-bit mode, BYTE = VIL.
C.1
Factory Locked Extended Block
In devices where the Extended Block is factory locked, the Security Identification Number is written to the Extended Block address space (see Table 36: Extended block address and data) in the factory. The DQ7 bit is set to `1' and the Extended Block cannot be unprotected.
C.2
Customer Lockable Extended Block
A device where the Extended Block is customer lockable is delivered with the DQ7 bit set to `0' and the Extended Block unprotected. It is up to the customer to program and protect the Extended Block but care must be taken because the protection of the Extended Block is not reversible. There are two ways of protecting the Extended Block:
Issue the Enter Extended Block command to place the device in Extended Block mode, then use the In-System Technique with RP either at VIH or at VID (refer to Section D.2: In-System Technique and to the corresponding flowcharts, Figure 27 and Figure 28, for a detailed explanation of the technique). Issue the Enter Extended Block command to place the device in Extended Block mode, then use the Programmer Technique (refer to, Section D.1: Programmer Technique and to the corresponding flowcharts, Figure 25 and Figure 26, for a detailed explanation of the technique).
Once the Extended Block is programmed and protected, the Exit Extended Block command must be issued to exit the Extended Block mode and return the device to Read mode.

Block Protection
Appendix D
Block Protection
Block protection can be used to prevent any operation from modifying the data stored in the memory. The blocks are protected in groups, refer to Appendix A: Block addresses, Table 28 and Table 29 for details of the Protection Groups. Once protected, Program and Erase operations within the protected group fail to change the data. There are three techniques that can be used to control Block Protection, these are the Programmer technique, the In-System technique and Temporary Unprotection. Temporary Unprotection is controlled by the Reset/Block Temporary Unprotection pin, RP; this is described in the Signal Descriptions section.
D.1
Programmer Technique
The Programmer technique uses high (VID) voltage levels on some of the bus pins. These cannot be achieved using a standard microprocessor bus, therefore the technique is recommended only for use in Programming Equipment. To protect a group of blocks follow the flowchart in Figure 25: Programmer Equipment Group Protect flowchart. To unprotect the whole chip it is necessary to protect all of the groups first, then all groups can be unprotected at the same time. To unprotect the chip follow Figure 26: Programmer Equipment Chip Unprotect flowchart. Table 37: Programmer technique bus operations, BYTE = VIH or VIL, gives a summary of each operation. The timing on these flowcharts is critical. Care should be taken to ensure that, where a pause is specified, it is followed as closely as possible. Do not abort the procedure before reaching the end. Chip Unprotect can take several seconds and a user message should be provided to show that the operation is progressing.
D.2
In-System Technique
The In-System technique requires a high voltage level on the Reset/Blocks Temporary Unprotect pin, RP(1). This can be achieved without violating the maximum ratings of the components on the microprocessor bus, therefore this technique is suitable for use after the memory has been fitted to the system. To protect a group of blocks follow the flowchart in Figure 27: In-System Equipment Group Protect flowchart. To unprotect the whole chip it is necessary to protect all of the groups first, then all the groups can be unprotected at the same time. To unprotect the chip follow Figure 28: In-System Equipment Chip Unprotect flowchart. The timing on these flowcharts is critical. Care should be taken to ensure that, where a pause is specified, it is followed as closely as possible. Do not allow the microprocessor to service interrupts that will upset the timing and do not abort the procedure before reaching the end. Chip Unprotect can take several seconds and a user message should be provided to show that the operation is progressing.
Note:
RP can be either at VIH or at VID when using the In-System Technique to protect the Extended Block.

2. A Write to Buffer and Program Abort and Reset must be issued to return the device in Read mode. 3. When the block address is specified, any address in the selected block address space is acceptable. However when loading Write Buffer address with data, all addresses must fall within the selected Write Buffer page. 4. DQ7 must be checked since DQ5 and DQ7 may change simultaneously. 5. If this flowchart location is reached because DQ5='1', then the Write to Buffer and Program command failed. If this flowchart location is reached because DQ1='1', then the Write to Buffer and Program command aborted. In both cases, the appropriate reset command must be issued to return the device in Read mode: a Reset command if the operation failed, a Write to Buffer and Program Abort and Reset command if the operation aborted. 6. See Table 10 and Table 11, for details on Write to Buffer and Program command sequence.
