| TH58NS100DC TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS 2 TM 1-GBIT (128M 8 BITS) CMOS NAND E PROM (128M BYTE SmartMedia DESCRIPTION ) The TH58NS100 is a single 3.3-V 1-Gbit (1,107,296,256) bit NAND Electrically Erasable and Programmable Read-Only Memory (NAND E2PROM) organized as 528 bytes 32 pages 8192 blocks. The device has a 528-byte static register which allows program and read data to be transferred between the register and the memory cell array in 528-byte increments. The Erase operation is implemented in a single block unit (16 Kbytes + 512 bytes: 528 bytes 32 pages). The TH58NS100 is a serial-type memory device which utilizes the I/O pins for both address and data input/output as well as for command inputs. The Erase and Program operations are automatically executed. The TH58NS100DC is a SmartMediaTM with ID and each device has 128 bit unique ID number embedded in the device. This unique ID number is applicable to image files, music files, electronic books, and so on where copyright protection is required. The data stored in the TH58NS100DC needs to comply with the data format standardized by the SSFDC Forum in order to maintain compatibility with other SmartMediaTM systems.

The device pin-outs are configured as shown in Figure 1. Command Latch Enable: CLE The CLE input signal is used to control loading of the operation mode command into the internal command register. The command is latched into the command register from the I/O port on the rising edge of the WE signal while CLE is High. 1 2 3 4 5 6 7 8 9 10 11 VSS CLE ALE WE WP I/O1 I/O2 I/O3 I/O4 VSS VSS Address Latch Enable: ALE The ALE signal is used to control loading of either address information or input data into the internal address/data register. Address information is latched on the rising edge of WE if ALE is High. Input data is latched if ALE is Low. Chip Enable: CE 22 21 20 19 18 17 16 15 14 13 12 The device goes into a low-power Standby mode when CE Figure 1. Pinout goes High during a Read operation. The CE signal is ignored when device is in Busy state ( RY/ BY = L), such as during a Program or Erase operation, and will not enter Standby mode even if the CE input goes High. The CE signal must stay Low during the Read mode Busy state to ensure that memory array data is correctly transferred to the data register. VCC CE RE RY/BY GND LVD I/O8 I/O7 I/O6 I/O5 VCC Write Enable: WE The WE signal is used to control the acquisition of data from the I/O port. Read Enable: RE The RE signal controls serial data output. Data is available tREA after the falling edge of RE . The internal column address counter is also incremented (Address = Address + 1) on this falling edge. I/O Port: I/O1~I/O8 The I/O1 to I/O8 pins are used as a port for transferring address, command and input/output data to and from the device. Write Protect: WP The WP signal is used to protect the device from accidental programming or erasing. The internal voltage regulator is reset when WP is Low. This signal is usually used for protecting the data during the power-on/off sequence when input signals are invalid. Ready/Busy: RY / BY The RY/ BY output signal is used to indicate the operating condition of the device. The RY/ BY signal is in Busy state ( RY/ BY = L) during the Program, Erase and Read operations and will return to Ready state ( RY/ BY = H) after completion of the operation. The output buffer for this signal is an open drain. Low Voltage Detect: LVD The LVD signal is used to detect the power supply voltage level. 2001-03-21 20/43 TH58NS100DC Schematic Cell Layout and Address Assignment The Program operation works on page units while the Erase operation works on block units.

Refer to Figure 3 below for timing details and the block diagram. CLE CE WE ALE RE RY/BY M I/O 00H N Busy M Start-address input 527 Select page N Figure 3. Read mode (1) operation Cell array A data transfer operation from the cell array to the register starts on the rising edge of WE in the fourth cycle (after the address information has been latched). The device will be in Busy state during this transfer period. The CE signal must stay Low after the fourth address input and during Busy state. After the transfer period the device returns to Ready state. Serial data can be output synchronously with the RE clock from the start pointer designated in the address input cycle. Read Mode (2) CLE CE WE ALE RE RY/BY M I/O 01H N Busy Start-address input 256 M 527 Select page N Figure 4. Read mode (2) operation Cell array The operation of the device after input of the 01H command is the same as that of Read mode (1). If the start pointer is to be set after column address 256, use Read mode (2). However, for a Sequential Read, output of the next page starts from column address 0. 2001-03-21 23/43 TH58NS100DC Read Mode (3) Read mode (3) has the same timing as Read modes (1) and (2) but is used to access information in the extra 16-byte redundancy area of the page. The start pointer is therefore set to a value between byte 512 and byte 527. CLE CE WE ALE RE RY/BY Busy 50H A0 to A3 Addresses bits A0 to A3 are used to set the start pointer for the redundant memory cells, while A4 to A7 are ignored. Once a "50H" command has been issued, the pointer moves to the redundant cell locations and only those 16 cells can be addressed, regardless of the value of the A4-to-A7 address. (A "00H" command is necessary to move the pointer back to the 0-to-511 main memory cell location.) I/O 512 527 Figure 5.

When the page address reaches the next block address, read command (00H/01H/50H) and address inputs are needed. 2001-03-21 24/43 TH58NS100DC Status Read The device has two Status Read commands. One is Status Read (1) command "70H" and the other is Status Read (2) command "71H". The device automatically implements the execution and verification of the Program and Erase operations. The Status Read function is used to monitor the Ready/Busy status of the device, determine the result (pass/fail) of a Program or Erase operation, and determine whether the device is in Protect mode. The device status is output via the I/O port on the RE clock after a Status Read command "70H" or "71H" input. The resulting information of Status Read (1) command "70H" is outlined in Table 5 below and the resulting information of Status Read (2) command "71H" is outlined in the explanation for Multi Block Program and Multi Block Erase toward the end of this document.

The sequence of command, address and data input is shown below. (Refer to the detailed timing chart.) Pass 80 10 70 Status Read command I/O Data input Address Data input Program command input 0 to 527 command Fail RY/BY RY/BY automatically returns to Ready after completion of the operation. Data input Program Selected page Reading & verification The data is transferred (programmed) from the register to the selected page on the rising edge of WE following input of the "10H" command. After programming, the programmed data is transferred back to the register to be automatically verified by the device. If the programming does not succeed, the Program/Verify operation is repeated by the device until success is achieved or until the maximum loop number set in the device is reached. Figure 7. Auto Page Program operation Auto Block Erase The Auto Block Erase operation starts on the rising edge of WE after the Erase Start command "D0H" which follows the Erase Setup command "80H". This two-cycle process for Erase operations acts as an ertra layer of protection from aceidental erasure of data due to external noise. The device automatically executes the Erase and Verify operations.

Chip 0, District 0: Block 0, Block 4, Block 8, Block 12, ***.., Block 4092 Chip 0, District 1: Block 1, Block 5, Block 9, Block 13, ***.., Block 4093 Chip 0, District 2: Block 2, Block 6, Block 10, Block 14, ***.., Block 4094 Chip 0, District 3: Block 3, Block 7, Block 11, Block 15, ***.., Block 4095 Chip 1, District 0: Block 4096, Block 4100, Block 4104, Block 4108, ***.., Block 8188 Chip 1, District 1: Block 4097, Block 4101, Block 4105, Block 4109, ***.., Block 8189 Chip 1, District 2: Block 4098, Block 4102, Block 4106, Block 4110, ***.., Block 8190 Chip 1, District 3: Block 4099, Block 4103, Block 4107, Block 4111, ***.., Block 8191 Address input restriction for the Multi Block Program operation In selecting the blocks for the Multi Block Program operation, following is the restriction and acceptance. (Restriction) It is prohibited to select blocks across 2-chips. Maximum one block should be selected from each District. The data input operation should be started from the same number page of the each selected block and then, the page number in the blocks should be same number at the same time programming. (Acceptance) There is no order limitation of the District for the address input. Any number of the District can be select for the programming. So, for example, following operation is in acceptance. (80) [District 2] (11) (80) [District 0] (11) (80) [District 1] (15) It requires no mutual address relation between the selected blocks from each District. Operating restriction during the Multi Block Program operation (Restriction) Starting from 1st page data input, until issuing "10H" command, any other command out of defined sequence can not be issued except Status Read command and Reset command. (Acceptance) The data input operation can be terminated with "10H" command instead of "15H" command in the middle of the page number in the block. In this case the Status represents the reflected value accumulated from 1st page programming of this sequence and up to the last page programming terminated by "10H" command. Status Read operation Untill the Ready condition after the programming terminated by "10H" command, effective bit in the Status data is limited on Ready/Busy bit. In other words, Pass/Fail condition can be checked only in the Ready condition after "10H" command. 2001-03-21 29/43 TH58NS100DC Multi Block Erase The device carries out a Multi Block Erase operation when it receives a "D0H" command after some sets of the address have been input. After the "D0H" command, the total results of Erase operation is shown through the Status Read (2) command "71H". Pass D0 71 Status Read command I/O Fail RY/BY The Status discription is following.

(Restriction) It is prohibited to select blocks across 2-chips. Maximum one block should be selected from each District. (Acceptance) There is no order limitation of the District for the address input. Any number of the Districts can be select for the erase operation. So, for example, following operation is in acceptance. (60) [District 2] (60) [District 0] (60) [District 1] (D0) It requires no mutual address relation between the selected blocks from each District. 2001-03-21 30/43 TH58NS100DC Reset The Reset mode stops all operations. For example, in the case of a Program or Erase operation the internally generated voltage is discharged to 0 volts and the device enters Wait state. The response to an "FFH" Reset command input during the various device operations is as follows: When a Reset (FFH) command is input during programming Figure 8. 80 10 FF 00 Internal VPP RY/BY tRST (max 10 ms) When a Reset (FFH) command is input during erasing Figure 9.

Power-on/off Sequence VIL In order to operate this device stably, after VCC becomes 2.8 V, it recommends starting access after about 200 ms. (2) Status after power-on The following sequence is necessary because some input signals may not be stable at power-on. Power on FF Reset Figure 16. (3) Prohibition of unspecified commands The operation commands are listed in Table 3. Input of a command other than those specified in Table 3 is prohibited. Stored data may be corrupted if an unknown command is entered during the command cycle. (4) Restriction of command while Busy state During Busy state, do not input any command except 70H, 71H and FFH. (5) Acceptable commands after Serial Input command "80H" Once the Serial Input command "80H" has been input, do not input any command other than the Program Execution command "10H", "11H" or "15H" or the Reset command "FFH". If a command other than "10H", "11H", "15H" or "FFH" is input, the Program operation is not performed. 80 XX 10 For this operation the "FFH" command is needed. Command other than Programming cannot be executed. "10H", "11H", "15H" or "FFH" 2001-03-21 34/43 TH58NS100DC (6) Addressing for program operation Within a block, the pages must be programmed consecutively from the LSB (least significant bit) page of the block to MSB (most significant bit) page of the block.

Status Read Status output The device status can be read out by inputting the Status Read command "70H" in Read mode. Once the device has been set to Status Read mode by a "70H" command, the device will not return to Read mode. Therefore, a Status Read during a Read operation is prohibited. However, when the Read command "00H" is input during [A], Status mode is reset and the device returns to Read mode. In this case, data output starts automatically from address N and address input is unnecessary 2001-03-21 35/43 TH58NS100DC (8) Pointer control for "00H", "01H" and "50H" The device has three Read modes which set the destination of the pointer. Table 7 shows the destination of the pointer, and Figure 14 is a block diagram of their operations. Table 8.

Data input 2001-03-21 39/43 TH58NS100DC (12) Several programming cycles on the same page (Partial Page Program) A page can be divided into up to 3 segments. Each segment can be programmed individually as follows: 1st programming Data Pattern 1 All 1s 2nd programming All 1s Data Pattern 2 All 1s nth programming All 1s Data Pattern 3 Result Data Pattern 1 Data Pattern 2 Data Pattern 3 Figure 24. Note: The input data for unprogrammed or previously programmed page segments must be "1" (i.e. the inputs for all page bytes outside the segment which is to be programmed should be set to all "1"). (13) Note regarding the RE signal RE The internal column address counter is incremented synchronously with the RE clock in Read mode. Therefore, once the device has been set to Read mode by a "00H", "01H" or "50H" command, the internal column address counter is incremented by the RE clock independently of the address input timing, If the RE clock input pulses start before the address input, and the pointer reaches the last column address, an internal read operation (array to register) will occur and the device will enter Busy state. (Refer to Figure 25.) Address input I/O 00H/01H/50H WE RE RY/BY Figure 25. Hence the RE clock input must start after the address input. 2001-03-21 40/43 TH58NS100DC (14) Invalid blocks (bad blocks) The device contains unusable blocks. Therefore, the following issues must be recognized: Referring to the Block status area in the redundant area allows the system to detect bad blocks in the accordance with the physical data format issued by the SSFDC Forum. Detect the bad blocks by checking the Block Status Area at the system power-on, and do not access the bad blocks in the following routine. The number of valid blocks at the time of shipment is as follows: MIN Bad Block Valid (Good) Block Number 8032 TYP. 3/4 MAX 8192 UNIT Block Bad Block Figure 26. (15) Failure phenomena for Program and Erase operations The device may fail during a Program or Erase operation. The following possible failure modes should be considered when implementing a highly reliable system. FAILURE MODE Block Page Single Bit Erase Failure Programming Failure Programming Failure 1(R)0 DETECTION AND COUNTERMEASURE SEQUENCE Status Read after Erase (R) Block Replacement Status Read after Program (R) Block Replacement (1) Block Verify after Program (R) Retry (2) ECC * * ECC: Error Correction Code Block Replacement Program Error occurs Buffer memory Block A When an error happens in Block A, try to reprogram the data into another (Block B) by loading from an external buffer. Then, prevent further system accesses to Block A (by creating a bad block table or by using an another appropriate scheme). Block B Figure 27. Erase When an error occurs for an Erase operation, prevent future accesses to this bad block (again by creating a table within the system or by using another appropriate scheme). (16) Chattering of Connector There may be contact chattering when the device is inserted or removed from a connector. This chattering may cause damage to the data in the device. Therefore, sufficient time must be allowed for contact bouncing to subside when a system is designed with SmartMediaTM. (17) The device is formatted to comply with the Physical and Logical Data Format of the SSFDC Forum at the time of shipping. 2001-03-21 41/43 TH58NS100DC Handling Precaution (1) (2) (3) Avoid bending or subjecting the card to sudden impact. Avoid touching the connectors so as to avoid damage from static electricity. This card should be kept in the antistatic film case when not in use. Toshiba cannot accept, and hereby disclaims liability for, any damage to the card including data corruption that may occur because of mishandling. How to read out unique ID number The 128 bit unique ID number is embedded in the device. The procedure to read out the ID number is available using special command which is provided under a non-disclosure agreement. SSFDC Forum The SSFDC Forum is a voluntary organization intended to promote the SmartMediaTM, a small removable NAND flash memory card. The SSFDC Forum standardized the following specifications in order to keep the compatibility of SmartMediaTM in systems. The latest specifications issued by the Forum must be referenced when a system is designed with SmartMediaTM, especially with large capacity SmartMediaTM. SmartMediaTM SmartMediaTM SmartMediaTM Electrical Specifications Physical Format Specification Logical Format Specification Some electrical specifications in this data sheet show differences from the Forum's electrical specification. Complying with the Forum's electrical specification maintains compatibility with other SmartMedias. Please refer following SSFDC Forum's URL to get the detailed information of each specification.
