GENERAL DESCRIPTION
Offered in 2Gx8bit, the K9GAG08X0M is a 16G-bit NAND Flash Memory with spare 512M-bit. The device is offered in 2.7V and 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 800µs on the 4,224-byte page and an erase operation can be performed in typical 1.5ms on a (512K+16K)byte
block. Data in the data register can be read out at 25ns cycle time per byte. 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. The K9GAG08X0M is an optimum solution for large nonvolatile
storage applications such as solid state file storage and other portable applications requiring non-volatility.

PIN DESCRIPTION
Pin Name
Pin Function
I/O0 ~ I/O7
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 high-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 in program or erase operation. Regarding CE control during
read operation, refer to ’Page read’ section of Device operation.
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 write/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 high-z condition when the chip is deselected or when outputs are disabled.

NO CONNECTION
Lead is not internally connected.
NOTE : Connect all VCC and VSS pins of each device to common power supply outputs.
Do not leave VCC or VSS disconnected.

Product Introduction
The K9GAG08X0M is a 16,896Mbit(17,716,740,096 bit) memory organized as 524,288 rows(pages) by 4,224x8 columns. Spare 128
columns are located from column address of 4,096~4,223. A 4,224-byte data register is 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. A cell has 2-bit data. Total 2,162,688 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 4,096 separately erasable 512K-byte blocks. It indicates that the bit by bit erase operation is prohibited on the K9GAG08X0M.
The K9GAG08X0M 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. The 2112M-byte physical space
requires 32 addresses, thereby requiring five cycles for addressing : 2 cycles of column address, 3 cycles of row address, in that
order. Page Read and Page Program need the same five address cycles following the required command input. In Block Erase operation, however, only three row address cycles are used. Device operations are selected by writing specific commands into the command register. Table 1 defines the specific commands of the K9GAG08X0M.
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
data-input cycles are removed, system performance for solid-state disk application is significantly increased.

NOTE :
1. The device may include initial invalid blocks when first shipped. Additional invalid blocks may develop while being used. The number of valid blocks is
presented with both cases of invalid blocks considered. Invalid blocks are defined as blocks that contain one or more bad bits which cause status failure during program and erase operation. Do not erase or program factory-marked bad blocks. Refer to the attached technical notes for appropriate
management of initial invalid blocks.
2. The 1st block, which is placed on 00h block address, is guaranteed to be a valid block at the time of shipment.
3. The number of valid blocks is on the basis of single plane operations, and this may be decreased with two plane operations.
* : Each K9GAG08U0M chip in the K9LBG08U1M has Maximum 100 invalid blocks

NAND Flash Technical Notes
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 Samsung.
The information regarding the initial invalid block(s) is called 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 at the time of shipment.
Identifying Initial Invalid Block(s)
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 in the spare area. Samsung makes sure that the last page of every initial invalid
block has non-FFh data at the column address of 4,096.The initial invalid block information is also erasable in most cases, and 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(Figure 3). Any intentional erasure of the initial invalid block information is prohibited.

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 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 4,224byte
data 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 µ-seconds, de-activating CE during the data-loading and serial access
would provide significant savings in power consumption.

Device Operation
PAGE READ
Page read is initiated by writing 00h-30h to the command register along with five address cycles. After initial power up, 00h command
is latched. Therefore only five address cycles and 30h command initiates that operation after initial power up. The 4,224 bytes of data
within the selected page are transferred to the data registers in less than 60µs(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.
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.

PAGE PROGRAM
The device is programmed basically on a page basis, and the number of consecutive partial page programming operation within the
same page without an intervening erase operation must not exceed 1 time for the 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 4,224bytes 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.
The serial data loading period begins by inputting the Serial Data Input command(80h), followed by the five 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.
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 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/O 6) 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/O 0) may be
checked(Figure 8). 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.

COPY-BACK PROGRAM
Copy-Back program with Read for Copy-Back is configured to quickly and efficiently rewrite data stored in one page without data reloading when the bit error is not in data stored. Since the time-consuming re-loading cycles are removed, the system performance is
improved. 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 4,224-byte
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/O 6) of the Status Register. When
the Copy-Back Program is complete, the Write Status Bit(I/O 0) may be checked(Figure 10 & Figure 11). The command register
remains in Read Status command mode until another valid command is written to the command register.
During copy-back program, data modification is possible using random data input command (85h) as shown in Figure11.

BLOCK ERASE
The Erase operation is done on a block basis. Block address loading is accomplished in three cycles initiated by an Erase Setup
command(60h). Only address A20 to A31 is valid while A13 to A19 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.
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/O 0) may be checked. Figure 12 details the sequence.

TWO-PLANE PAGE READ
Two-Plane Page Read is an extension of Page Read, for a single plane with 4,224 byte page registers. Since the device is equipped
with two memory planes, activating the two sets of 4,224 byte page registers enables a random read of two pages. Two-Plane Page
Read is initiated by repeating command 60h followed by three address cycles twice. In this case only same page of same block can
be selected from each plane.
After Read Confirm command(30h) the 8,448 bytes of data within the selected two page are transferred to the data registers in less
than 60us(tR). The system controller can detect the completion of data transfer(tR) by monitoring the output of R/B pin.
Once the data is loaded into the data registers, the data output of first plane can be read out by issuing command 00h with Five
Address Cycles, command 05h with two column address and finally E0h. The data output of second plane can be read out using the
identical command sequences. The restrictions for Two-Plane Page Program are shown in Figure 13. Two-Plane Read must be
used in the block which has been programmed with Two-Plane Page Program.

TWO-PLANE PAGE PROGRAM
Two-Plane Page Program is an extension of Page Program, for a single plane with 4,224 byte page registers. Since the device is
equipped with two memory planes, activating the two sets of 4,224 byte page registers enables a simultaneous programming of two
pages.
After writing the first set of data up to 4,224 byte into the selected page register, Dummy Page Program command (11h) instead of
actual Page Program (10h) is inputted to finish data-loading of the first plane. Since no programming process is involved, R/B
remains in Busy state for a short period of time(tDBSY). Read Status command (70h/F1h) may be issued to find out when the device
returns to Ready state by polling the Ready/Busy status bit(I/O 6). Then the next set of data for the other plane is inputted after the
81h command and address sequences. After inputting data for the last plane, actual True Page Program(10h) instead of dummy
Page Program command (11h) must be followed to start the programming process. The operation of R/B and Read Status is the
same as that of Page Program. Status bit of I/O 0 is set to "1" when any of the pages fails. Restriction in addressing with Two-Plane
Page Program is shown in Figure14.

TWO-PLANE BLOCK ERASE
Basic concept of Two-Plane Block Erase operation is identical to that of Two-Plane Page Program. Up to two blocks, one from each
plane can be simultaneously erased. Standard Block Erase command sequences (Block Erase Setup command(60h) followed by
three address cycles) may be repeated up to twice for erasing up to two blocks. Only one block should be selected from each plane.
The Erase Confirm command(D0h) initiates the actual erasing process. The completion is detected by monitoring R/B pin or Ready/
Busy status bit (I/O 6).

READ STATUS
The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether
the program or erase operation is completed successfully. After writing 70h or F1h 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 table 2 for specific 70h Status Register definitions and table 3 for specific
F1h 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.

READ ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Five read cycles sequentially output the manufacturer code(ECh), and the device code and 3rd cycle ID, 4th cycle ID, 5th cycle
respectively. The command register remains in Read ID mode until further commands are issued to it. Figure 18 shows the operation
sequence.

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. Refer to Table 4 for device status after reset operation. 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 19 below.

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 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. 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(Fig 20). Its value can be
determined by the following guidance.

DATA PROTECTION & POWER UP SEQUENCE
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 2V. WP pin provides hardware protection and is recommended to be kept at VIL
during power-up and power-down. A recovery time of minimum 10µs is required before internal circuit gets ready for any command
sequences as shown in Figure 21. The two step command sequence for program/erase provides additional software protection.
