GENERAL DESCRIPTION
The K9F1608W0A is a 2M(2,097,152)x8bit NAND Flash Memory with a spare 64K(65,536)x8bit. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. A program operation programs the 264-byte page in typically 250μs and an erase operation can be performed in typically 2ms on a 4K-byte block.
Data in the page can be read out at 80ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command inputs. The on-chip write controller automates all program and erase system functions, including pulse repetition, where required, and internal verify and margining of data. Even the write-intensive systems can take advantage of the K9F1608W0A extended reliability of 1,000,000 program/erase cycles by providing either ECC(Error Correction Code) or real time mapping-out algorithm. These algorithms have been implemented in many mass storage applications and also the spare 8bytes of a page combined with the other 256 bytes can be utilized by system-level ECC.
The K9F1608W0A is an optimum solution for large nonvolatile storage application such as solid state storage, digital voice recorder, digital still camera and other portable applications requiring nonvolatility.

PRODUCT INTRODUCTION
The K9F1608W0A is a 16.5Mbit(17,301,504 bit) memory organized as 8192 rows by 264 columns. Spare eight columns are located from column address of 256 to 263. A 264-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 to form a NAND structure. Each of the 16 cells resides in a different page. A block consists of the 16 pages formed by one NAND structures, totaling 2,112 NAND structures of 16 cells. The array organization is shown in Figure 2. The program and read operations are executed on a page basis, while the erase operation is executed on block basis. The memory array consists of 512 separately or grouped erasable 4K-byte blocks. It indicates that the bit by bit erase operation is prohibited on the K9F1608W0A.
The K9F1608W0A has addresses multiplexed into 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 through I/O`s 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 for Block Erase command which requires two cycles : a cycle for erase-setup and another for erase-execution after block address loading. The 2M byte physical space requires 21 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 the required command input. In Block Erase operation, however, only the two 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 K9F1608W0A.

PIN DESCRIPTION
Command Latch Enable(CLE)
The CLE input controls the path activation 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.
Address Latch Enable(ALE)
The ALE input controls the path activation for address and input data to the internal address/data register. Addresses are latched on the rising edge of WE with ALE high, and input data is latched when ALE is low.
Chip Enable(CE)
The CE input is the device selection control. When CE goes high during a read operation the device is returned to standby mode. However, when the device is in the busy state during program or erase, CE high is ignored, and does not return the device to standby mode.
Write Enable(WE)
The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE pulse.
Read Enable(RE)
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.
I/O Port : I/O 0 ~ I/O 7
The I/O pins are used to input command, address and data, and to outputs data during read operations. The I/O pins float to high-z when the chip is deselected or the outputs are disabled.
Write Protect (WP)
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.
Ready/Busy(R/B)
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 return 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 outputs are disabled.
Power Line(VCC & VCCQ)
The VCCQ is the power supply for I/O interface logic. It is electrically isolated from main power line(VCC=2.7~5.5V) for supporting 5V tolerant I/O with 5V power supply at VCCQ.

NOTE :
1.Minimum DC voltage is -0.3V on input/output pins. During transitions, this level may undershoot to -2.0V for periods <30ns. Maximum DC voltage on input/output pins is VCCQ+0.3V which, during transitions, may overshoot to VCC+2.0V for periods <20ns.
2.Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

NOTE : 1. If CE goes high within 30ns after the rising edge of the last RE, R/B will not return to VOL.
2.The time to Ready depends on the value of the pull-up resistor tied R/B pin.
3.To break the sequential read cycle, CE must be held high for longer time than tCEH.
