The device is offered in 3.3V VCC. Its NAND cell provides the most cost effective solution for the solid state mass storage market. A program operation can be performed in typical 200us on the 2,112-byte(x8) or 1,056-word(x16) page and an erase operation can be performed in typical 1.5ms on a (128K+4K) bytes(x8) or (64K+2K) words(x16) block. Data in the data register can be read out at 25ns cycle time per byte(x8) or word(x16). The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write controller automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the writeintensive systems can take advantage of this device’s extended reliability of 100K program/erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm. This device is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable applications requiring non-volatility.

The I/O pins float to Hi-Z when the chip is deselected or when the outputs are disabled. I/O8 ~ I/O15(2) DATA INPUTS/OUTPUTS The I/O pins are used to input command, address and data, and to output data during read operations. The I/O pins float to Hi-Z when the chip is deselected or when the outputs are disabled. CLE COMMAND LATCH ENABLE The CLE input controls the activating path for commands sent to the command register. When active high, commands are latched into the command register through the I/O ports on the rising edge of the WE# signal. ALE ADDRESS LATCH ENABLE The ALE input controls the activating path for address to the internal address registers. Addresses are latched on the rising edge of WE# with ALE high. CE# CHIP ENABLE The CE# input is the device selection control. When the device is in the Busy state, CE# high is ignored, and the device does not return to standby mode. RE# READ ENABLE The RE# input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the falling edge of RE# which also increments the internal column address counter by one. WE# WRITE ENABLE The WE# input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE# pulse. WP# WRITE PROTECT The WP# pin provides inadvertent program/erase protection during power transitions. The internal high voltage generator is reset when the WP# pin is active low. R/B# READY/BUSY OUTPUT The R/B# output indicates the status of the device operation. When low, it indicates that a program, erase or random read operation is in process and returns to high state upon completion. It is an open drain output and does not float to Hi-Z condition when the chip is deselected or when outputs are disabled. VCC POWER VCC is the power supply for device. VSS GROUND N.C.

Page 7 IS34MC01GA08 IS34MC01GA16 Product Introduction D A TA SH EE T This device is a 1,056Mbits (1,107,296,256 bits) memory organized as 65,539 rows (pages) by 2,112-byte(x8) or 1,056-word(x16) columns. Spare 64-byte(x8) or 32-word(x16) columns are located from column address of 2,048 to 2,111(x8) or 1,024 to 1,055(x16). A 2,112-byte(x8) or 1,056-word(x16) data register and 2,112-byte(x8) or 1,056-word(x16) cache register are serially connected to each other. Those serially connected registers are connected to memory cell arrays for accommodating data transfer between the I/O buffers and memory cells during page read and page program operations. The memory array is made up of 32 cells that are serially connected to form a NAND structure. Each of the 32 cells resides in a different page. A block consists of two NAND structured strings. A NAND structure consists of 32 cells. Total 1,081,344 NAND cells reside in a block. The program and read operations are executed on a page basis, while the erase operation is executed on a block basis. The memory array consists of 1,024 separately erasable 128K-byte(x8) or 64K-word(x16) blocks. It indicates that the bit by bit erase operation is prohibited on the device. This device uses addresses multiplexed scheme. This scheme dramatically reduces pin counts and allows systems upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written through I/O's by bringing WE# to low while CE# is low. Those are latched on the rising edge of WE#. Command Latch Enable (CLE) and Address Latch Enable (ALE) are used to multiplex command and address respectively, via the I/O pins. Some commands require one bus cycle. For example, Reset Command, Status Read Command, etc require just one cycle bus. Some other commands, like page read and block erase and page program, require two cycles: one cycle for setup and the other cycle for execution. The total physical space requires 28(x8) or 27(x16) addresses, thereby requiring four cycles for addressing: 2 cycle of column address, 2 cycles of row address, in that order. Page Read and Page Program need the same four address cycles following the required command input. In Block Erase operation, however, only the 2 cycles of row address are used. Device operations are selected by writing specific commands into the command register. Below table defines the specific commands of this device. The device provides cache program in a block. It is possible to write data into the cache registers while data stored in data registers are being programmed into memory cells in cache program mode. The program performance may be dramatically improved by cache program when there are lots of pages of data to be programmed. In addition to the enhanced architecture and interface, the device incorporates copy-back program feature from one page to another page without need for transporting the data to and from the external buffer memory. Since the time-consuming serial access and datainput cycles are removed, system performance for solid-state disk application is significantly increased.

Page 11 IS34MC01GA08 IS34MC01GA16 NAND Flash Technical Notes Initial Invalid Block(s) EE T Initial invalid blocks are defined as blocks that contain one or more initial invalid bits whose reliability is not guaranteed by PFC. Information regarding the initial invalid block(s) is so called as the initial invalid block information. Devices with initial invalid block(s) have the same quality level as devices with all valid blocks and have the same AC and DC characteristics. An initial invalid block(s) does not affect the performance of valid block(s) because it is isolated from the bit line and the common source line by a select transistor. The system design must be able to mask out the initial invalid block(s) via address mapping. The 1st block, which is placed on 00h block address, is guaranteed to be a valid block up to 1K program/erase cycles with 1 bit/528 bytes ECC. Identifying Initial Invalid Block(s) N C ED D A TA SH All device locations are erased (FFh) except locations where the initial invalid block(s) information is written prior to shipping. The initial invalid block(s) status is defined by the 1st byte(x8) or 1st word(x16) in the spare area. PFC makes sure that either the 1st or 2nd page of every initial invalid block has non-FFh data at the 1st byte(x8) or 1st word(x16) column address in the spare area. Since the initial invalid block information is also erasable in most cases, it is impossible to recover the information once it has been erased. Therefore, the system must be able to recognize the initial invalid block(s) based on the initial invalid block information and create the initial invalid block table via the following suggested flow chart. Any intentional erasure of the initial invalid block information is prohibited. VA Error in write or read operation A D Within its life time, the additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the block failure rate. The following possible failure modes should be considered to implement a highly reliable system. In the case of status read failure after erase or program, block replacement should be done. Because program status fail during a page program does not affect the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased empty block and reprogramming the current target data and copying the rest of the replaced block. In case of Read, ECC must be employed. To improve the efficiency of memory space, it is recommended that the read failure due to single bit error should be reclaimed by ECC without any block replacement. The block failure rate in the qualification report does not include those reclaimed blocks.

The internal 2,112 bytes(x8) or 1,056 words(x16) page registers are utilized as separate buffers for this operation and the system design gets more flexible. In addition, for voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE# during the data-loading and reading would provide significant savings in power consumption.

After initial power up, 00h command is latched. Therefore only four address cycles and 30h command initiates that operation after initial power up. The 2,112 bytes(x8) or 1,056 words(x16) of data within the selected page are transferred to the data registers in less than tR. The system controller can detect the completion of this data transfer (tR) by analyzing the output of R/B# pin. Once the data in a page is loaded into the data registers, they may be read out in 25ns cycle time by sequentially pulsing RE#. The repetitive high to low transitions of the RE# clock make the device output the data starting from the selected column address up to the last column address. EE T The device may output random data in a page instead of the consecutive sequential data by writing random data output command. The column address of next data, which is going to be out, may be changed to the address which follows random data output command. Random data output can be operated multiple times regardless of how many times it is done in a page. Read Operation SH CE# CLE TA ALE WE# tR R/B# I/Ox D A RE# 00h Address (4cycles) 30h Col.

The number of consecutive partial page programming operation within the same page without an intervening erase operation must not exceed 4 times for a single page. The addressing should be done in sequential order in a block. A page program cycle consists of a serial data loading period in which up to 2,112 bytes(x8) or 1,056 words(x16) of data may be loaded into the data register, followed by a non-volatile programming period where the loaded data is programmed into the appropriate cell. EE T The serial data loading period begins by inputting the Serial Data Input command (80h), followed by the four cycle address inputs and then serial data loading. The words other than those to be programmed do not need to be loaded. The device supports random data input in a page. The column address for the next data, which will be entered, may be changed to the address which follows random data input command (85h). Random data input may be operated multiple times regardless of how many times it is done in a page. SH The Page Program confirm command (10h) initiates the programming process. Writing 10h alone without previously entering the serial data will not initiate the programming process. The internal write state controller automatically executes the algorithms and timings necessary for program and verify, thereby freeing the system controller for other tasks. Once the program process starts, the Read Status Register command may be entered, with RE# and CE# low, to read the status register. The system controller can detect the completion of a program cycle by monitoring the R/B output, or the Status bit (I/O6) of the Status Register. Only the Read Status command and Reset command are valid while programming is in progress. When the Page Program is complete, the Write Status Bit (I/O0) may be checked. The internal write verify detects only errors for "1"s that are not successfully programmed to "0"s. The command register remains in Read Status command mode until another valid command is written to the command register. A D VA N C Random Data Input In a page ED D A TA Program & Read Status Operation Page 26 IS34MC01GA08 IS34MC01GA16 Cache Program Cache Program is an extension of Page Program, which is executed with 2,112 byte(x8) or 1,056 words(x16) data registers, and is available only within a block. Since the device has 1 page of cache memory, serial data input may be executed while data stored in data register are programmed into memory cell. SH EE T After writing the first set of data up to 2,112 bytes(x8) or 1,056 words(x16) into the selected cache registers, Cache Program command (15h) instead of actual Page Program (10h) is inputted to make cache registers free and to start internal program operation. To transfer data from cache registers to data registers, the device remains in Busy state for a short period of time (tCBSY) and has its cache registers ready for the next data-input while the internal programming gets started with the data loaded into data registers. Read Status command (70h) may be issued to find out when cache registers become ready by polling the Cache-Busy status bit (I/O6). Pass/fail status of only the previous page is available upon the return to Ready state. When the next set of data is inputted with the Cache Program command, tCBSY is affected by the progress of pending internal programming. The programming of the cache registers is initiated only when the pending program cycle is finished and the data registers are available for the transfer of data from cache registers. The status bit (I/O5) for internal Ready/Busy may be polled to identity the completion of internal programming. If the system monitors the progress of programming only with R/B#, the last page of the target programming sequence must be programmed with actual Page Program command (10h). Note: A D 2. Since programming the last page does not employ caching, the program time has to be that of Page Program. However, if the previous program cycle with the cache data has not finished, the actual program cycle of the last page is initiated only after completion of the previous cycle, which can be expressed as the following formula. tPROG = Program time for the last page + Program time for the (last-1)th page – (Program command cycle time + Last page data loading time) VA 1.

TA D A Note: 1. 2. SH Page Copy-Back Program Operation EE T Copy-Back program with Read for Copy-Back is configured to quickly and efficiently rewrite data store in one page. The benefit is especially obvious when a portion of a block is updated and the rest of the block also needs to be copied to the newly assigned free block. Copy-Back operation is a sequential execution of Read for Copy-Back and of copy-back program with the destination page address. A read operation with “35h” command and the address of the source page moves the whole 2,112-byte(x8) or 1,056-word(x16) data into the internal data buffer. A bit error is checked by sequential reading the data output. In the case where there is no bit error, the data do not need to be reloaded. Therefore Copy-Back program operation is initiated by issuing Page-Copy Data-Input command (85h) with destination page address. Actual programming operation begins after Program Confirm command (10h) is issued. Once the program process starts, the Read Status Register command (70h) may be entered to read the status register. The system controller can detect the completion of a program cycle by monitoring the R/B# output, or the Status bit (I/O6) of the Status Register. When the Copy-Back Program is completed, the Write Status Bit (I/O0) may be checked. The command register remains in Read Status command mode until another valid command is written to the command register. This operation is allowed only within the same memory plane. It’s prohibited to operate Copy-Back program from an odd address page (source page) to an even address (target page) or from an even address page (source page) to an odd address page (target page). Therefore, the Copy-Back program is permitted just between odd address pages or even address pages. A D VA N C ED Page Copy-Back Program Operation with Random Data Input Page 28 IS34MC01GA08 IS34MC01GA16 Block Erase The Erase operation is done on a block basis. Block address loading is accomplished in two cycles initiated by an Erase Setup command (60h). Only address A18 to A27(x8) or A17 to A26(x16) is valid while A12 to A17(x8) or A11 to A16(x16) is ignored. The Erase Confirm command (D0h) following the block address loading initiates the internal erasing process. This two-step sequence of setup followed by execution command ensures that memory contents are not accidentally erased due to external noise conditions. T At the rising edge of WE# after the erase confirm command input, the internal write controller handles erase and erase-verify. When the erase operation is completed, the Write Status Bit (I/O0) may be checked.

After writing 70h command to the command register, a read cycle outputs the content of the Status Register to the I/O pins on the falling edge of CE# or RE#, whichever occurs last. This two line control allows the system to poll the progress of each device in multiple memory connections even when R/B# pins are common-wired. RE# or CE# does not need to be toggled for updated status. Refer to below table for specific Status Register definitions. The command register remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read cycle, the read command (00h) should be given before starting read cycles. Page 30 IS34MC01GA08 IS34MC01GA16 Read ID The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of 00h. Four read cycles sequentially output the manufacturer code (92h), and the device code and 3rd, 4th and 5th cycle ID respectively. The command register remains in Read ID mode until further commands are issued to it. x8 x16 92h 92h F1h C1h 80h 80h 4th Cycle 5th Cycle 95h D5h 40h 40h Description D A Maker Code Device Code Internal Chip Number, Cell Type, Number of Simultaneously Programmed Pages, Etc.

When the device is in busy state during random read, program or erase mode, the reset operation will abort these operations. The contents of memory cells being altered are no longer valid, as the data will be partially programmed or erased. The command register is cleared to wait for the next command, and the Status Register is cleared to value C0h when WP# is high. If the device is already in reset state a new reset command will be accepted by the command register. The R/B# pin changes to low for tRST after the Reset command is written. Refer to Figure below. Page 32 IS34MC01GA08 IS34MC01GA16 READY/BUSY# TA SH EE T The device has an R/B# output that provides a hardware method of indicating the completion of a page program, erase and random read completion. The R/B# pin is normally high but transitions to low after program or erase command is written to the command register or random read is started after address loading. It returns to high when the internal controller has finished the operation. The pin is an open-drain driver thereby allowing two or more R/B# outputs to be Or-tied.
