The write-buffer programming operation can be sus-
pended using the standard program suspend/resume
commands. Upon successful completion of the Write
Buffer Programming operation, the device is ready to
execute the next command.
The Write Buffer Programming Sequence can be
aborted in the following ways:
■ Load a value that is greater than the page buffer
■ Write to an address in a sector different than the
■ Write
■ Write data other than the Confirm Command after
The abort condition is indicated by DQ1 = 1, DQ7 =

toggle, and DQ5=0. A Write-to-Buffer-Abort Reset
command sequence must be written to reset the de-
vice for the next operation. Note that the full 3-cycle
Write-to-Buffer-Abort Reset command sequence is re-
quired when using Write-Buffer-Programming features
in Unlock Bypass mode.
Accelerated Program
The device offers accelerated program operations
through the ACC pin. When the system asserts V
the ACC pin, the device automatically enters the Un-
lock Bypass mode. The system may then write the
two-cycle Unlock Bypass program command se-
quence. The device uses the higher voltage on the
ACC pin to accelerate the operation. Note that the
ACC pin must not be at V
accelerated programming, or device damage may re-
sult.
Figure 5 illustrates the algorithm for the program oper-
ation. Refer to the
table in the AC Characteristics section for parameters,
and Figure 18 for timing diagrams.
