GENERAL DESCRIPTION
The device is a 128Mx8bit with spare 4Mx8bit capacity. The
device is offered in 1.8V VCC Power Supply. Its NAND cell
provides the most cost-effective solution for the solid state mass
storage market. The memory is divided into blocks that can be
erased independently so it is possible to preserve valid data
while old data is erased.
The device contains 1024 blocks, composed by 64 pages
consisting in two NAND structures of 32 series connected Flash
cells. A program operation allows to write the 1056-Word page in
typical 250us and an erase operation can be performed in typical
2ms on a 128K-Byte for device block.
Data in the page mode can be read out at 45ns cycle time per
Elite Semiconductor Memory Technology Inc.
Byte. The I/O pins serve as the ports for address and command
inputs as well as data input/output. The copy back function
allows the optimization of defective blocks management: when a
page program operation fails the data can be directly
programmed in another page inside the same array section
without the time consuming serial data insertion phase. The
cache program feature allows the data insertion in the cache
register while the data register is copied into the Flash array.
This pipelined program operation improves the program
throughput when long files are written inside the memory. A
cache read feature is also implemented. This feature allows to
dramatically improving the read throughput when consecutive
pages have to be streamed out. This device includes extra
feature: Automatic Read at Power Up.

Functions
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.
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.
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.
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 in program or
erase operation. Regarding CE control during read operation, refer to ’Page read’
section of Device operation.
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.
The WE input controls writes to the I/O port. Commands, address and data are
latched on the rising edge of the WE pulse.
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.
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.

Product Introduction
The device is a 1,056Mbit memory organized as 64K rows (pages) by 2,112x8 columns. Spare 64x8 columns are located from column
address of 2,048~2,111. A 2,112-byte data register is connected to memory cell arrays accommodating data transfer between the I/O
buffers and memory during page read and page program operations. 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 blocks. It
indicates that the bit-by-bit erase operation is prohibited on the device.
The device has addresses multiplexed into 8 I/Os. This scheme dramatically reduces pin counts and allows system 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.
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.

NAND Flash Technical Notes
Mask Out Initial Invalid Block(s)
Initial invalid blocks are defined as blocks that contain one or more initial invalid bits whose reliability is not guaranteed by ESMT. The
information regarding the initial invalid block(s) is 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) and Block Replacement Management
Unpredictable behavior may result from programming or erasing the defective blocks. The under figure illustrates an algorithm for
searching factory-mapped defects, and the algorithm needs to be executed prior to any erase or program operations.
A host controller has to scan blocks from block 0 to the last block using page read command and check the data at the column address
of 0 or 2,047. If the read data is not FFh, the block is interpreted as an invalid block. The initial invalid block information is erasable, and
which is impossible to be recovered once it has been erased. Therefore, the host controller must be able to recognize the initial invalid
block information and to create a corresponding table to manage block replacement upon erase or program error when additional
invalid blocks develop with Flash memory usage.
Algorithm for Bad Block Scanning
For (i=0; i<Num_of_LUs; i++)
{
For (j=0; j<Blocks_Per_LU; j++)
{
Defect_Block_Found=False;
Read_Page(lu=i, block=j, page=0);

Error in Write or Read operation
Within its lifetime, additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the actual data.
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 or verification failure due to single bit error be reclaimed by
ECC without any block replacement. The additional block failure rate does not include those reclaimed blocks.

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) pages of the block. Random page address programming is prohibited. In this case, the definition of LSB page is the LSB
among the pages to be programmed. Therefore, LSB page doesn’t need to be page 0.

System Interface Using CE Don’t Care
For an easier system interface, CE may be inactive during the data-loading or serial access as shown below. The internal 2,112byte
data registers are utilized as separate buffers for this operation and the system design gets more flexible. In addition, for voice or audio
applications that use slow cycle time on the order of μ-seconds, de-activating CE during the data-loading and serial access would
provide significant savings in power consumption.

Device Operation
Page Read
Upon initial device power up, the device defaults to Read mode. This operation is also initiated by writing 00h command, four-cycle
address, and 30h command. After initial power up, the 00h command can be skipped because it has been latched in the command
register. The 2,112Byte of data on a page are transferred to cache registers via data registers within 25us (tR). Host controller can
detect the completion of this data transfer by checking the R/ B output. Once data in the selected page have been loaded into cache
registers, each Byte can be read out in 45ns cycle time by continuously pulsing RE . The repetitive high-to-low transitions of RE
clock signal make the device output data starting from the designated column address to the last column address.
The device can output data at a random column address instead of sequential column address by using the Random Data Output
command. Random Data Output command can be executed multiple times in a page.
After power up, device is in read mode so 00h command cycle is not necessary to start a read operation.
A page read sequence is illustrated in under figure, where column address, page address are placed in between commands 00h and
30h. After tR read time, the R/ B de-asserts to ready state. Read Status command (70h) can be issued right after 30h. Host controller
can toggle RE to access data starting with the designated column address and their successive bytes.

Page Program
The device is programmed based on the unit of a page, and consecutive partial page programming on one page without intervening
erase operation is strictly prohibited. Addressing of page program operations within a block should be in sequential order. A complete
page program cycle consists of a serial data input cycle in which up to 2,112byte of data can be loaded into data register via cache
register, followed by a programming period during which the loaded data are programmed into the designated memory cells.
The serial data input cycle begins with the Serial Data Input command (80h), followed by a four-cycle address input and then serial
data loading. The bytes not to be programmed on the page do not need to be loaded. The column address for the next data can be
changed to the address follows Random Data Input command (85h). Random Data Input command may be repeated multiple times in
a page. The Page Program Confirm command (10h) starts the programming process. Writing 10h alone without entering data will not
initiate the programming process. The internal write engine automatically executes the corresponding algorithm and controls timing for
programming and verification, thereby freeing the host controller for other tasks. Once the program process starts, the host controller
can detect the completion of a program cycle by monitoring the R/ B output or reading the Status bit (I/O6) using the Read Status
command. Only Read Status and Reset commands are valid during programming. When the Page Program operation is completed,
the host controller can check the Status bit (I/O0) to see if the Page Program operation is successfully done. The command register
remains the Read Status mode unless another valid command is written to it.
A page program sequence is illustrated in under figure, where column address, page address, and data input are placed in between
80h and 10h. After tPROG program time, the R/ B de-asserts to ready state. Read Status command (70h) can be issued right after 10h.

Cache Program
Cache Program is an extension of Page Program, which is executed with 2,112 bytedata 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.
After writing the first set of data up to 2,112 bytes 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).
Cache Program (available only within a block)
Note:
1. 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.
2. tPROG = Program time for the last page + Program time for the (last-1)th page – (Program command cycle time + Last page data
loading time)

Copy-Back Program
Copy-Back Program is designed to efficiently copy data stored in memory cells without time-consuming data reloading when there is
no bit error detected in the stored data. The benefit is particularly obvious when a portion of a block is updated and the rest of the block
needs to be copied to a newly assigned empty block. Copy-Back operation is a sequential execution of Read for Copy-Back and of
Copy-Back Program with Destination address. A Read for Copy-Back operation with “35h” command and the Source address moves
the whole 2,112byte data into the internal buffer. The host controller can detect bit errors by sequentially reading the data output.
Copy-Back Program is initiated by issuing Page-Copy Data-Input command (85h) with Destination address. If data modification is
necessary to correct bit errors and to avoid error propagation, data can be reloaded after the Destination address. Data modification
can be repeated multiple times as shown in under figure. Actual programming operation begins when Program Confirm command (10h)
is issued. Once the program process starts, the Read Status command (70h) may be entered to read the status register. The host
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 complete, the Status Bit (I/O0) may be checked. The command register remains Read Status mode
until another valid command is written to it.

Block Erase
The block-based Erase operation is initiated by an Erase Setup command (60h), followed by a two-cycle row address, in which only
Plane address and Block address are valid while Page address is ignored. The Erase Confirm command (D0h) following the row
address starts the internal erasing process. The two-step command sequence is designed to prevent memory content from being
inadvertently changed by external noise. At the rising edge of WE after the Erase Confirm command input, the internal control logic
handles erase and erase-verify. When the erase operation is completed, the host controller can check Status bit (I/O0) to see if the
erase operation is successfully done. The under figure illustrates a block erase sequence, and the address input (the first page address
of the selected block) is placed in between commands 60h and D0h. After tBERASE erase time, the R/ B de-asserts to ready state. Read
Status command (70h) can be issued right after D0h to check the execution status of erase operation.
Block Erase Operation
Read Status
A status register on the device is used to check whether program or erase operation is completed and whether the operation is
completed successfully. After writing 70h command to the command register, a read cycle outputs the content of the status register to
I/O pins on the falling edge of CE or RE , whichever occurs last. These two commands allow 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 toggle for status
change.
The command register remains in Read Status mode unless other commands are issued to it. Therefore, if the status register is read
during a random read cycle, a read command (00h) is needed to start read cycles.

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 (C8h), and the device code and 3rd, 4th cycle ID respectively. The
command register remains in Read ID mode until further commands are issued to it.

Reset
The device offers a reset feature, executed by writing FFh to the command register. 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 the figure below.

Cache Read
Cache Read is an extension of Page Read, and is available only within a block. The normal Page Read command (00h-30h) is always
issued before invoking Cache Read. After issuing the Cache Read command (31h), read data of the designated page (page N) are
transferred from data registers to cache registers in a short time period of tDCBSYR, and then data of the next page (page N+1) is
transferred to data registers while the data in the cache registers are being read out. Host controller can retrieve continuous data and
achieve fast read performance by iterating Cache Read operation. The Read Start for Last Page Cache Read command (3Fh) is used
to complete data transfer from memory cells to data registers.

Ready / Busy
The device has a 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 transition 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. Because pull-up resistor value is related to tr (R/ B )
and current drain during busy (ibusy), an appropriate value can be obtained with the following reference chart. Its value can be
determined by the following guidance.

Data Protection & Power Up Sequence
The timing sequence shown in the figure below is necessary for the power-on/off sequence.
The device internal initialization starts after the power supply reaches an appropriate level in the power on sequence. During the
initialization the device R/ B signal indicates the Busy state as shown in the figure below. In this time period, the acceptable
commands are 70h.
The WP signal is useful for protecting against data corruption at power on/off.

One-Time Programmable (OTP) Operations
This flash device offers one-time programmable memory area. Thirty full pages of OTP data are available on the device, and the entire
range is guaranteed to be good. The OTP area is accessible only through the OTP commands.
The OTP area leaves the factory in an unwritten state. The OTP area cannot be erased, whether it is protected or not. Protecting the
OTP area prevents further programming of that area.
The OTP area is only accessible while in OTP operation mode. To set the device to OTP operation mode, issue the Set Feature
(EFh-90h-01h) command. When the device is in OTP operation mode, subsequent Read and/or Page Program are applied to the OTP
area. When you want to come back to normal operation, you need to use EFh-90h-00h for OTP mode release. Otherwise, device will
stay in OTP mode.
To program an OTP page, issue the Serial Data Input (80h) command followed by 4 address cycles. The first two address cycles are
column address. For the third cycle, select a page in the range of 00h through 1Dh. The fourth cycle is fixed at 00h. Next, up to 2,112
bytes of data can be loaded into data register. The bytes other than those to be programmed do not need to be loaded. This device
supports Random Data Input (85h) command, which can be operated multiple times in a page. The column address for the next data to
be entered may be changed to the address follows the Random Data Input command. The Page Program confirm (10h) command
initiates the programming process. The internal control logic automatically executes the programming algorithm, timing and verification.
Please note that no partial-page program is allowed in the OTP area. In addition, the OTP pages must be programmed in the
ascending order. A programmed OTP page will be automatically protected.
Similarly, to read data from an OTP page, set the device to OTP operation mode and then issue the Read (00h-30h) command. The
device may output random data (not in sequential order) in a page by writing Random Data Output (05h-E0h) command, which can be
operated multiple times in a page. The column address for the next data to be output may be changed to the address follows the
Random Data Output command.
All pages in the OTP area will be protected simultaneously by issuing the Set Feature (EFh-90h-03h) command to set the device to
OTP protection mode. After the OTP area is protected, no page in the area is programmable and the whole area cannot be
unprotected.
The Read Status (70h) command is the only valid command for reading status in OTP operation mode.
