(10,11)
Notes:
10.
CE
and
WE
must be LOW for WRITE cycle.
11.
OE
is LOW for this WRITE cycle to show t
and t
.
12. If
CE
goes HIGH simultaneously with
WE
HIGH, the output remains
in a high impedance state
13. Write Cycle Time is measured from the last valid address to the first
transitioning address.
