Multi-Chip Package MEMORY
128M Bit (16Mx8) Nand Flash Memory / 8M Bit (1Mx8/512Kx16) Full CMOS SRAM
The K5P2880YCM featuring 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 FLASHs 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.

NAND FLASH PRODUCT INTRODUCTION
Table 1. COMMAND SETS
NOTE : 1. The 00h command defines starting address of the 1st half of registers.
The 01h command defines starting address of the 2nd half of registers. After data access on the 2nd half of register by the 01h command, the status pointer is automatically moved to the 1st half register(00h) on the next cycle.

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
are serially connected like NAND structure. Each of the 16 cells resides in a different page. A block consists of the 32 pages f
ormed
by one NAND structures, totaling 8448 NAND structures of 16 cells. The array organization is shown in Figure 2. Program and rea
d
operations are executed on a page basis, while erase operation is executed on a block basis. The memory array consists of 1024
blocks, and a block is separately erasable by 16K-byte unit. It indicates that the bit by bit erase operation is prohibited o
n the NAND
Flash.
The NAND Flash has addresses multiplexed with 8 I/O
s. 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 throug
h
I/Os by bringing WE to low while CE is low. Data is 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. 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
by writing specific commands into command register. Table 1 defines the specific commands of the NAND Flash.

tR
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.

Figure 6. Block Erase Operation
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.

Figure 7. Read ID Operation
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.
Figure 8. RESET Operation
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.
