1) In the word-wide mode, upper byte data (D8-D15) is ignored.
2) IA=ID Code Address : A0=VIL (Manufacturer's Code) : A0=VIH (Device Code), ID=ID Code,
/BYTE =VIL : A-1, A1-A18 = VIL, /BYTE =VIH : A1-A18 = VIL
3) SRD = Status Register Data
4) WA=Write Address, WD=Write Data.
/BYTE =VIL : Write Address and Write Data must be provided sequentially from 00H to FFH for A-1-A6.
Page size is 256Byte (256byte x 8bit), /BYTE =VIH : Write Address and Write Data must be provided
sequentially from 00H to 7FH for A0-A6. Page size is 128word (128word x 16bit).
5) BA = Block Address ( Addresses except Block Address mest be VIH.)
6) DQ6 provides Block Lock Status, DQ6 = 1 : Block Unlock, DQ6 = 0 : Block Locked.
7) Sleep command (F0H) put the device into the sleep mode after completing the current operation. The active current is reduced to deep power -down levels.
The Read Array command (FFH) must be written to get the device out of sleep mode.

D6 provides Lock Status of each block after writing the Read Lock Status command (71H).
In case of TSOP package, /WP pin must not be switched during performing Read / Write operations or WSM Busy (WSMS = 0).

*The RY/BY is an open drain output pin and indicates status of the internal WSM. When low,it indicates that the WSM is Busy performing an operation.
A pull-up resistor of 10K-100K Ohms is required to allow the RY/BY signal to transition high indicating a Ready WSM condition.
*D3 indicates the block status after the page programming. When D3 is "1", the page has the over-programed cell . If over-program occures, the device is block
fail. However if D3 is "1", please try the block erase to the block. The block may revive.

In the word-wide mode, the same data as D7-0 is read out from D15-8.
A9 = VHH Mode : A9 = 11.5V~13.0V Set A9 to VHH min.200ns before falling edge of /CE in ready status. Min.200ns after return to VIH ,device can't be accessed.
A1~A8, A10~A18, /CE,/OE = VIL, /WE = VIH
D15/A-1 = VIL (/BYTE = L)
