Legend:
X = Don’t care
RA = Read Address of memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on falling edge of WE# or
CE# pulse, whichever happens later.

All values are in hexadecimal.
Shaded cells indicate read cycles. All others are write cycles.
During unlock and command cycles, when lower address bits are
555 or 2AA as shown in table, address bits above A11 and data
bits above DQ7 are don’t care.
No unlock or command cycles required when device is in read
mode.
Reset command is required to return to read mode (or to erase-
suspend-read mode if previously in Erase Suspend) when device
is in autoselect mode, or if DQ5 goes high while device is
providing status information.
Fourth cycle of the autoselect command sequence is a read
cycle. Data bits DQ15–DQ8 are don’t care. Except for RD, PD
and WC. See
information.
Device ID must be read in three cycles.
If WP# protects highest address sector, data is 98h for factory
locked and 18h for not factory locked. If WP# protects lowest
address sector, data is 88h for factory locked and 08h for not
factor locked.

PD = Program Data for location PA. Data latches on rising edge of
WE# or CE# pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or
erased. Address bits A21–A15 uniquely select any sector.
WBL = Write Buffer Location. Address must be within same write
buffer page as PA.
WC = Word Count. Number of write buffer locations to load minus 1.
