GENERAL DESCRIPTION
The K5P2880YCMfeaturing single 3.0V power supply is a Multi
ChipPackage Memory which combines 128Mbit Nand Flash and
8Mbit full CMOS SRAM.
The 128Mbit Flash memory is organized as 16M x8 bit and the
8Mbit SRAM is organized as 1M x8 or 512K x16 bit. In 128Mb
NAND Flash a 528-byte page program can be typically achieved
within 300us and an 16K-byte block erase can be typically
achieved within 2ms. In serial read operation, a byte can be read
by 50ns. The I/O pins serve as the ports for address and data
input/output as well as command inputs. Even the write-intensive
systems can take advantage of the FLASH′s extended reliability
of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm. These algorithms
have been implemented in many mass storage applications and
also the spare 16 bytes of a page combined with the other 512
bytes can be utilized by system-level ECC. The 8Mbit SRAM supports the low data retention voltage for battery backup operation
with low current.
The K5P2880YCM is suitable for use in data memory of mobil
communication system to reduce not only mount area but also
power consumption. This device is available in 69-ball TBGA
Type.

The NAND Flash is a 132Mbit(138,412,032 bit) memory organized as 32,768 rows(pages) by 528 columns. Spare 16 columns are
located in 512 to 527 column address. A 528-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 memory array is made up of 16 cells that
ormed
d
operations are executed on a page basis, while erase operation is executed on a block basis. The memory array consists of 1024
n the NAND
s. This scheme dramatically reduces pin counts and allows systems
h
. Command Latch Enable(CLE) and Address
Latch Enable(ALE) are used to multiplex command and address respectively, via the I/O pins. All commands require one bus cycle
except Page Program command and Block Erase command which require two cycles: one cycle for setup and another for execution.
The 16M byte physical space requires 24 addresses, thereby requiring three cycles for byte-level addressing: column address, low
row address and high row address, in that order. Page Read and Page Program need the same three address cycles following
required command input. In Block Erase operation, however, only two row address cycles are used. Device operations are selected

are serially connected like NAND structure. Each of the 16 cells resides in a different page. A block consists of the 32 pages f
by one NAND structures, totaling 8448 NAND structures of 16 cells. The array organization is shown in Figure 2. Program and rea
blocks, and a block is separately erasable by 16K-byte unit. It indicates that the bit by bit erase operation is prohibited o
Flash.
The NAND Flash has addresses multiplexed with 8 I/O′
upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written throug
I/O′s by bringing WE to low while CE is low. Data is latched on the rising edge of WE
by writing specific commands into command register. Table 1 defines the specific commands of the NAND Flash.

FLASH MEMORY OPERATION
PAGE READ
Upon initial device power up, the device status is initially Read1 command(00h) latched. This operation is also initiated by writing
00h to the command register along with three address cycles. Once the command is latched, it does not need to be written for the following page read operation. Two types of operation are available : random read, serial page read. The random read mode is enabled
when the page address is changed. The 528 bytes of data within the selected page are transferred to the data registers in less than
10µs(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 registers, they may be read out by sequential RE pulse of 50ns period cycle. High to low transitions of the
RE clock take out the data from the selected column address up to the last column address.
Read1 and Read2 commands determine pointer which selects either main area or spare area. The spare area(512 to 527 bytes)
may be selectively accessed by writing the Read2 command. Addresses A0 to A3 set the starting address of spare area while
addresses A4 to A7 are ignored. To move the pointer back to the main area, Read1 command(00h/01h) is needed. Figures 3
through 4 show typical sequence and timing for each read operation.
Figure 3,4 details the sequence.

PAGE PROGRAM
The device is programmed basically on a page basis, but it does allow multiple partial page programming of a byte or consecutive
bytes up to 528, in a single page program cycle. The number of consecutive partial page programming operation within the same
page without an intervening erase operation should not exceed 2 for main array and 3 for spare array. The addressing may be done
in any random order in a block. A page program cycle consists of a serial data loading period in which up to 528 bytes of data may be
loaded into the page register, followed by a non-volatile programming period where the loaded data is programmed into the appropriate cell. Serial data loading can be started from 2nd half array by moving pointer. About the pointer operation, please refer to the
attached technical notes.
The serial data loading period begins by inputting the Serial Data Input command(80h), followed by the three cycle address input and
then serial data loading. The bytes other than those to be programmed do not need to be loaded.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-control automatically executes the algorithms and timings necessary for program and
verify, thereby freeing the CPU 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 CPU 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 5). 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.

BLOCK ERASE
The Erase operation is done on a block(8K Byte) basis. Block address loading is accomplished in two cycles initiated by an Erase
Setup command(60h). Only address A14 to A23 is valid while A9 to A13 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 state-control handles erase and erase-verify.
When the erase operation is completed, the Write Status Bit(I/O 0) may be checked.
Figure 6 details the sequence.

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 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 4 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, a read command(00h or 50h) should be given before sequential page read cycle.

READ ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Two read cycles sequentially output the manufacture code(ECh), and the device code (73h) respectively. The command register remains in Read ID mode until further commands are issued to it. Figure 7 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 modes, the reset operation will abort these operation. The contents of memory cells being altered are no
longer valid, as the data will be partially programmed or erased. Internal address registers are cleared to "0"s and data registers to
"1"s. 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 5 for device status after reset operation. If the device is already in reset state a new reset command will not be
accepted to by the command register. The R/B pin transitions to low for tRST after the Reset command is written. Reset command is
not necessary for normal operation. Refer to Figure 8 below.
