TYPE
BYTE-SELECT ADDRESS: Selects between high and low byte when device is in x8
mode. This address is latched in x8 Data Writes. Not used in x16 mode (i.e., the A
input buffer is turned off when BYTE is high).
WORD-SELECT ADDRESSES: Select a word within one 64K block. A
1 of 1024 rows, and A
latched during Data Writes.
BLOCK-SELECT ADDRESSES: Select 1 of 32 Erase blocks. These addresses are
latched during Data Writes, Erase and Lock-Block operations.
LOW-BYTE DATA BUS: Inputs data and commands during CUI write cycles.
Outputs array, buffer, identifier or status data in the appropriate Read mode. Floated
when the chip is de-selected or the outputs are disabled.
HIGH-BYTE DATA BUS : Inputs data during x16 Data-Write operations. Outputs
array, buffer or identifier data in the appropriate Read mode; not used for Status
register reads. Floated when the chip is de-selected or the outputs are disabled.
CHIP ENABLE INPUTS : Activate the device’s control logic, input buffers, decoders and
sense amplifiers. With either CE

low, any current or pending WSM operation(s) are terminated, and the device is
reset. All Status registers return to ready (with all status flags cleared). After
returning, the device is in read array mode.
OUTPUT ENABLE: Gates device data through the output buffers when low. The
outputs float to tri-state off when OE
NOTE:
WRITE ENABLE: Controls access to the CUI, Page Buffers, Data Queue Registers
and Address Queue Latches. WE is active low, and latches both address and data

READY/BUSY: Indicates status of the internal WSM. When low, it indicates that the
WSM is busy performing an operation. RY/BY# high indicates that the WSM is ready
for new operations (or WSM has completed all pending operations), or Erase is
