HY27SS(08/16)121M Series HY27US(08/16)121M Series 512Mbit (64Mx8bit / 32Mx16bit) NAND Flash
DESCRIPTION
The HYNIX HY27(U/S)SXX121M series is a family of non-volatile Flash memories that use NAND cell technology. The devices operate 3.3V and 1.8V voltage supply. The size of a Page is either 528 Bytes (512 + 16 spare) or 264 Words (256 + 8 spare) depending on whether the device has a x8 or x16 bus width. The address lines are multiplexed with the Data Input/ Output signals on a multiplexed x8 or x16 Input/ Output bus. This interface reduces the pin count and makes it possible to migrate to other densities without changing the footprint. Each block can be programmed and erased over 100,000 cycles. To extend the lifetime of NAND Flash devices it is strongly recommended to implement an Error Correction Code (ECC). A Write Protect pin is available to give a hardware protection against program and erase operations. The devices feature an open-drain Ready/Busy output that can be used to identify if the Program/ Erase/Read (PER) Controller is currently active. 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 Copy Back command is available to optimize the management of defective blocks. When a Page Program operation fails, the data can be programmed in another page without having to resend the data to be programmed.
The devices are available in the following packages: - 48-TSOP1 (12 x 20 x 1.2 mm) - 48-WSOP1 (12 x 17 x 0.7 mm) - 63-FBGA (8.5 x 15 x 1.2 mm, 6 x 8 ball array, 0.8mm pitch) Three options are available for the NAND Flash family: - Automatic Page 0 Read after Power-up, which allows the microcontroller to directly download the boot code from page 0. - Chip Enable Dont Care, which allows code to be directly downloaded by a microcontroller, as Chip Enable transitions during the latency time do not stop the read operation. - A Serial Number, which allows each device to be uniquely identified. The Serial Number options is subject to an NDA (Non Disclosure Agreement) and so not described in the datasheet. For more details of this option contact your nearest HYNIX Sales office. Devices are shipped from the factory with Block 0 always valid and the memory content bits, in valid blocks, erased to '1'.

MEMORY ARRAY ORGANIZATION The memory array is made up of NAND structures where 16 cells are connected in series. The memory array is organized in blocks where each block contains 32 pages. The array is split into two areas, the main area and the spare area. The main area of the array is used to store data whereas the spare area is typically used to store Error Correction Codes, software flags or Bad Block identification. In x8 devices the pages are split into a main area with two half pages of 256 Bytes each and a spare area of 16 Bytes. In the x16 devices the pages are split into a 256 Word main area and an 8 Word spare area. Refer to Figure 8, Memory Array Organization. Bad Blocks The NAND Flash 528 Byte/ 264 Word Page devices may contain Bad Blocks, that is blocks that contain one or more invalid bits whose reliability is not guaranteed. Additional Bad Blocks may develop during the lifetime of the device. The Bad Block Information is written prior to shipping (refer to Bad Block Management section for more details). The values shown include both the Bad Blocks that are present when the device is shipped and the Bad Blocks that could develop later on. These blocks need to be managed using Bad Blocks Management, Block Replacement or Error Correction Codes.

SIGNAL DESCRIPTIONS See Figure 1, Logic Diagram and Table 1, Signal Names, for a brief overview of the signals connected to this device. Inputs/Outputs (I/O0-I/O7) Input/Outputs 0 to 7 are used to input the selected address, output the data during a Read opertion or input a command or data during a Write operation. The inputs are latched on the rising edge of Write Enable. I/O0-I/O7 can be left floating when the device is deselected or the outputs are disabled. Inputs/Outputs (I/O8-I/O15) Input/Outputs 8 to 15 are only available in x16 devices. They are used to output the data during a Read operation or input data during a Write operation. Command and Address Inputs only require I/O0 to I/O7. The inputs are latched on the rising edge of Write Enable. I/O8-I/O15 can be left floating when the device is deselected or the outputs are disabled. Address Latch Enable (ALE) The Address Latch Enable activates the latching of the Address inputs in the Command Interface. When ALE is high, the inputs are latched on the rising edge of Write Enable. Command Latch Enable (CLE) The Command Latch Enable activates the latching of the Command inputs in the Command Interface. When CLE is high, the inputs are latched on the rising edge of Write Enable. Chip Enable (CE) The Chip Enable input activates the memory control logic, input buffers, decoders and sense amplifiers. When Chip Enable is low, VIL, the device is selected. If Chip Enable goes high, VIH, while the device is busy, the device remains selected and does not go into standby mode. When the device is executing a Sequential Row Read operation, Chip Enable must be held low (from the second page read onwards) during the time that the device is busy (tBLBH1). If Chip Enable goes high during tBLBH1 the operation is aborted. Read Enable (RE) The Read Enable, RE, controls the sequential data output during Read operations. Data is valid tRLQV after the falling edge of RE. The falling edge of RE also increments the internal column address counter by one. Write Enable (WE). The Write Enable input, WE, controls writing to the Command Interface, Input Address and Data latches. Both addresses and data are latched on the rising edge of Write Enable. During power-up and power-down a recovery time of 1us (min) is required before the Command Interface is ready to accept a command. It is recommended to keep Write Enable high during the recovery time. Write Protect (WP). The Write Protect pin is an input that gives a hardware protection against unwanted program or erase operations. When Write Protect is Low, VIL, the device does not accept any program or erase operations. It is recommended to keep the Write Protect pin Low, VIL, during power-up and power-down.

Ready/Busy (RB) The Ready/Busy output, RB, is an open-drain output that can be used to identify if the Program/ Erase/ Read (PER) Controller is currently active. When Ready/Busy is Low, VOL, a read, program or erase operation is in progress. When the operation completes Ready/Busy goes High, VOH. The use of an open-drain output allows the Ready/ Busy pins from several memories to be connected to a single pullup resistor. A Low will then indicate that one, or more, of the memories is busy. Refer to the Ready/Busy Signal Electrical Characteristics section for details on how to calculate the value of the pull-up resistor. VCC Supply Voltage VCC provides the power supply to the internal core of the memory device. It is the main power supply for all operations (read,program and erase). An internal voltage detector disables all functions whenever VCC is below 2.5V (for 3V devices) or 1.5V (for 1.8V devices) to protect the device from any involuntary program/erase during power-transitions. Each device in a system should have VCC decoupled with a 0.1uF capacitor. The PCB track widths should be sufficient to carry the required program and erase currents VSS Ground Ground, VSS, is the reference for the power supply. It must be connected to the system ground. BUS OPERATIONS There are six standard bus operations that control the memory. Each of these is described in this section, see Tables 2, Bus Operations, for a summary. Command Input Command Input bus operations are used to give commands to the memory. Command are accepted when Chip Enable is Low, Command Latch Enable is High, Address Latch Enable is Low and Read Enable is High. They are latched on the rising edge of the Write Enable signal. Only I/O0 to I/O7 are used to input commands. See Figure 21 and Table 14 for details of the timings requirements. Address Input Address Input bus operations are used to input the memory address. Four bus cycles are required to input the addresses for the 512Mb devices (refer to Tables 3 and 4, Address Insertion). The addresses are accepted when Chip Enable is Low, Address Latch Enable is High, Command Latch Enable is Low and Read Enable is High. They are latched on the rising edge of the Write Enable signal. Only I/O0 to I/O7 are used to input addresses. See Figure 22 and Table 14 for details of the timings requirements. Data Input Data Input bus operations are used to input the data to be programmed. Data is accepted only when Chip Enable is Low, Address Latch Enable is Low, Command Latch Enable is Low and Read Enable is High. The data is latched on the rising edge of the Write Enable signal. The data is input sequentially using the Write Enable signal. See Figure 23 and Tables 14 and 15 for details of the timings requirements.

Data Output Data Output bus operations are used to read: the data in the memory array, the Status Register, the Electronic Signature and the Serial Number. Data is output when Chip Enable is Low, Write Enable is High, Address Latch Enable is Low, and Command Latch Enable is Low. The data is output sequentially using the Read Enable signal. See Figure 24 and Table 15 for details of the timings requirements. Write Protect Write Protect bus operations are used to protect the memory against program or erase operations. When the Write Protect signal is Low the device will not accept program or erase operations and so the contents of the memory array cannot be altered. The Write Protect signal is not latched by Write Enable to ensure protection even during power-up. Standby When Chip Enable is High the memory enters Standby mode, the device is deselected, outputs are disabled and power consumption is reduced.

COMMAND SET All bus write operations to the device are interpreted by the Command Interface. The Commands are input on I/O0-I/ O7 and are latched on the rising edge of Write Enable when the Command Latch Enable signal is high. Device operations are selected by writing specific commands to the Command Register. The two-step command sequences for program and erase operations are imposed to maximize data security. The Commands are summarized in Table 5, Commands. Table 5: Command Set

DEVICE OPERATIONS
Pointer Operations As the NAND Flash memories contain two different areas for x16 devices and three different areas for x8 devices (see Figure 8) the read command codes (00h, 01h, 50h) are used to act as pointers to the different areas of the memory array (they select the most significant column address). The Read A and Read B commands act as pointers to the main memory area. Their use depends on the bus width of the device. - In x16 devices the Read A command (00h) sets the pointer to Area A (the whole of the main area) that is Words 0 to 255. - In x8 devices the Read A command (00h) sets the pointer to Area A (the first half of the main area) that is Bytes 0 to 255, and the Read B command (01h) sets the pointer to Area B (the second half of the main area) that is Bytes 256 to 511. In both the x8 and x16 devices the Read C command (50h), acts as a pointer to Area C (the spare memory area) that is Bytes 512 to 527 or Words 256 to 263. Once the Read A and Read C commands have been issued the pointer remains in the respective areas until another

HY27SS(08/16)121M Series HY27US(08/16)121M Series 512Mbit (64Mx8bit / 32Mx16bit) NAND Flash
pointer code is issued. However, the Read B command is effective for only one operation, once an operation has been executed in Area B the pointer returns automatically to Area A. The pointer operations can also be used before a program operation, that is the appropriate code (00h, 01h or 50h) can be issued before the program command 80h is issued (see Figure 9).

Read Memory Array Each operation to read the memory area starts with a pointer operation as shown in the Pointer Operations section. The device defaults to Read A mode after powerup or a Reset operation. Devices, where page0 is read automatically at power-up, are available on request. When reading the spare area addresses: - A0 to A3 (x8 devices) - A0 to A2 (x16 devices) are used to set the start address of the spare area while addresses: - A4 to A7 (x8 devices) - A3 to A7 (x16 devices) are ignored. Once the Read A or Read C commands have been issued they do not need to be reissued for subsequent read operations as the pointer remains in the respective area. However, the Read B command is effective for only one operation, once an operation has been executed in Area B the pointer returns automatically to Area A and so another Read B command is required to start another read operation in Area B. Once a read command is issued three types of operations are available: Random Read, Page Read and Sequential Row Read. Random Read Each time the command is issued the first read is Random Read. Page Read After the Random Read access the page data is transferred to the Page Buffer in a time of tWHBH (refer to Table 15 for value). Once the transfer is complete the Ready/Busy signal goes High. The data can then be read out sequentially (from selected column address to last column address) by pulsing the Read Enable signal. Sequential Row Read After the data in last column of the page is output, if the Read Enable signal is pulsed and Chip Enable remains Low then the next page is automatically loaded into the Page Buffer and the read operation continues. A Sequential Row Read operation can only be used to read within a block. If the block changes a new read command must be issued. Refer to Figures 12 and 13 for details of Sequential Row Read operations. To terminate a Sequential Row Read operation set the Chip Enable signal to High for more than tEHEL. Sequential Row Read is not available when the Sequential row read option is disabled.

Page Program The Page Program operation is the standard operation to program data to the memory array. The main area of the memory array is programmed by page, however partial page programming is allowed where any number of bytes (1 to 528) or words (1 to 264) can be programmed. The max number of consecutive partial page program operations allowed in the same page is one in the main area and two in the spare area. After exceeding this a Block Erase command must be issued before any further program operations can take place in that page. Before starting a Page Program operation a Pointer operation can be performed to point to the area to be programmed. Refer to the Pointer Operations section and Figure 9 for details. Each Page Program operation consists of five steps (see Figure 14): 1. one bus cycle is required to setup the Page Program command 2. four bus cycles are then required to input the program address (refer to Table 3) 3. the data is then input (up to 528 Bytes/ 264 Words) and loaded into the Page Buffer 4. one bus cycle is required to issue the confirm command to start the Program/ Erase/Read Controller. 5. The Program/ Erase/Read Controller then programs the data into the array. Once the program operation has started the Status Register can be read using the Read Status Register command. During program operations the Status Register will only flag errors for bits set to '1' that have not been successfully programmed to '0'. During the program operation, only the Read Status Register and Reset commands will be accepted, all other commands will be ignored. Once the program operation has completed the Program/ Erase/Read Controller bit SR6 is set to '1' and the Ready/ Busy signal goes High. The device remains in Read Status Register mode until another valid command is written to the Command Interface.

Copy Back Program The Copy Back Program operation is used to copy the data stored in one page and reprogram it in another page. The Copy Back Program operation does not require external memory and so the operation is faster and more efficient because the reading and loading cycles are not required. The operation is particularly useful when a portion of a block is updated and the rest of the block needs to be copied to the newly assigned block. If the Copy Back Program operation fails an error is signalled in the Status Register. However as the standard external ECC cannot be used with the Copy Back operation bit error due to charge loss cannot be detected. For this reason it is recommended to limit the number of Copy Back operations on the same data and/or to improve the performance of the ECC. The Copy Back Program operation requires three steps: - 1. The source page must be read using the Read A command (one bus write cycle to setup the command and then 4 bus write cycles to input the source page address). This operation copies all 264 Words/ 528 Bytes from the page into the Page Buffer. - 2. When the device returns to the ready state (Ready/Busy High), the second bus write cycle of the command is given with the 4 bus cycles to input the target page address. A25 must be the same for the Source and Target Pages. - 3. Then the confirm command is issued to start the P/E/R Controller. After a Copy Back Program operation, a partial page program is not allowed in the target page until the block has been erased. See Figure 15 for an example of the Copy Back operation.

Figure 15. Copy Back Operation Block Erase Erase operations are done one block at a time. An erase operation sets all of the bits in the addressed block to '1'. All previous data in the block is lost. An erase operation consists of three steps (refer to Figure 17): 1. One bus cycle is required to setup the Block Erase command. 2. Only three bus cycles for 512Mb devices are required to input the block address. The first cycle (A0 to A7) is not required as only addresses A14 to A25 (highest address depends on device density) are valid, A9 to A13 are ignored. In the last address cycle I/O0 to I/O7 must be set to VIL. 3. One bus cycle is required to issue the confirm command to start the P/E/R Controller.

Figure 17. Block Erase Operation Reset The Reset command is used to reset the Command Interface and Status Register. If the Reset command is issued during any operation, the operation will be aborted. If it was a program or erase operation that was aborted, the contents of the memory locations being modified will no longer be valid as the data will be partially programmed or erased. If the device has already been reset then the new Reset command will not be accepted. The Ready/Busy signal goes Low for tBLBH4 after the Reset command is issued. The value of tBLBH4 depends on the operation that the device was performing when the command was issued, refer to Table 15 for the values. Read Status Register The device contains a Status Register which provides information on the current or previous Program or Erase operation. The various bits in the Status Register convey information and errors on the operation. The Status Register is read by issuing the Read Status Register command. The Status Register information is present on the output data bus (I/O0- I/O7) on the falling edge of Chip Enable or Read Enable, whichever occurs last. When several memories are connected in a system, the use of Chip Enable and Read Enable signals allows the system to poll each device separately, even when the Ready/Busy pins are common-wired. It is not necessary to toggle the Chip Enable or Read Enable signals to update the contents of the Status Register. After the Read Status Register command has been issued, the device remains in Read Status Register mode until another command is issued. Therefore if a Read Status Register command is issued during a Random Read cycle a new read command must be issued to continue with a Page Read or Sequential Row Read operation. The Status Register bits are summarized in Table 6, Status Register Bits. Refer to Table 6 in conjunction with the following text descriptions. Write Protection Bit (SR7) The Write Protection bit can be used to identify if the device is protected or not. If the Write Protection bit is set to '1' the device is not protected and program or erase operations are allowed. If the Write Protection bit is set to '0' the device is protected and program or erase operations are not allowed.

P/E/R Controller Status Register bit SR6 has two different functions depending on the current operation. During all other operations SR6 acts as a P/E/R Controller bit, which indicates whether the P/E/R Controller is active or inactive. When the P/E/R Controller bit is set to '0', the P/E/R Controller is active (device is busy); when the bit is set to '1', the P/E/R Controller is inactive (device is ready). P/E/R Controller Bit (SR5) The Program/Erase/Read Controller bit indicates whether the P/E/R Controller is active or inactive. When the P/E/R Controller bit is set to '0', the P/E/R Controller is active (device is busy); when the bit is set to '1', the P/E/R Controller is inactive (device is ready). Error Bit (SR0) The Error bit is used to identify if any errors have been detected by the P/E/R Controller. The Error Bit is set to '1' when a program or erase operation has failed to write the correct data to the memory. If the Error Bit is set to '0' the operation has completed successfully. SR4, SR3 and SR2 are Reserved

Read Electronic Signature The device contains a Manufacturer Code and Device Code. To read these codes two steps are required: 1. first use one Bus Write cycle to issue the Read Electronic Signature command (90h) 2. then subsequent Bus Read operations will read the Manufacturer Code and the Device Code until another command is issued. Refer to Table, Read Electronic Signature for information on the addresses.

Automatic Page 0 Read at Power-Up Automatic Page 0 Read at Power-Up is an option available on all devices belonging to the NAND Flash 528 Byte/264 Word Page family. It allows the microcontroller to directly download boot code from page 0, without requiring any command or address input sequence. The Automatic Page 0 Read option is particularly suited for applications that boot from the NAND. Devices delivered with Automatic Page 0 Read at Power-Up can have the Sequential Row Read option either enabled ordisabled. Automatic Page 0 Read Description. At powerup, once the supply voltage has reached the threshold level, VCCth, all digital outputs revert to their reset state and the internal NAND device functions (reading, writing, erasing) are enabled. The device then automatically switches to read mode where, as in any read operation, the device is busy for a time tBLBH1 during the data is transferred to the Page Buffer. Once the data transfer is complete the Ready/Busy signal goes High. The data can then be read out sequentially on the I/O bus by pulsing the Read Enable, RE#, signal. Figures 18 and 19 show the power-up waveforms for devices featuring the Automatic Page 0 Read option.

Sequential Row Read Disabled If the device is delivered with Sequential row read disabled and Automatic Read Page 0 at Power-up, only the first page (Page 0) will be automatically read after the power-on sequence. Refer to Figure 18. Sequential Row Read Enabled If the device is delivered with the Automatic Page 0 Read option only (Sequential Row Read Enabled), the device will automatically enter Sequential Row Read mode after the power-up sequence, and start reading Page 0, Page 1, etc., until the last memory location is reached, each new page being accessed after a time tBLBH1. The Sequential Row Read operation can be inhibited or interrupted by de-asserting E (set to VIH) or by issuing a command. Refer to Figure 19.

Figure 19. Automatic Page 0 Read at power-up (Sequential Row Read Enable) Bad Block Management Devices with Bad Blocks have the same quality level and the same AC and DC characteristics as devices where all the blocks are valid. A Bad Block does not affect the performance of valid blocks because it is isolated from the bit line and common source line by a select transistor. The devices are supplied with all the locations inside valid blocks erased (FFh). The Bad Block Information is written prior to shipping. Any block where the 6th Byte/ 1st Word in the spare area of the 1st or 2nd page (if the 1st page is Bad) does not contain FFh is a Bad Block. The Bad Block Information must be read before any erase is attempted as the Bad Block Information may be erased. For the system to be able to recognize the Bad Blocks based on the original information it is recommended to create a Bad Block table following the flowchart shown in Figure 20. Block Replacement Over the lifetime of the device additional Bad Blocks may develop. In this case the block has to be replaced by copying the data to a valid block. These additional Bad Blocks can be identified as attempts to program or erase them will give errors in the Status Register. As the failure of a page program operation does not affect the data in other pages in the same block, the block can be replaced by re-programming the current data and copying the rest of the replaced block to an available valid block. The Copy Back Program command can be used to copy the data to a valid block.
See the "Copy Back Program" section for more details.

System Interface Using CE don't care
To simplify system interface, CE may be deasserted during data loading or sequential data-reading as shown below. So, it is possible to connect NAND Flash to a microprocessor. The only function that was removed from standard NAND Flash to make CE don't care read operation was disabling of the automatic sequential read function.

Ready/Busy Signal Electrical Characteristics Figures 32, 33 and 34 show the electrical characteristics for the Ready/Busy signal. The value required for the resistor RP can be calculated using the following equation:
where IL is the sum of the input currents of all the devices tied to the Ready/Busy signal. RP max is determined by the maximum value of tr.
