Write
With the chip enabled and the nonvolatile functions
inhibited, the Write Enable (
WE) pin will select the write
mode when driven to a low level. In this mode, the
address must be supplied for the byte being written.
After the set-up time (tAS), the input data must be
supplied to pins I/O0–I/O3. When these conditions, in-

cluding the write pulse width time (tWP) are met, the data
will be written to the specified location in the Static RAM.
A write function may also be initiated from the standby
mode by driving
WE low, inhibiting the nonvolatile func-
tions, supplying valid addresses, and then taking
CS low
and supplying input data.
