Parameter
Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
I
t
At any given temperature and voltage condition, t
The internal write time of the memory is defined by the overlap of CE LOW, and WE LOW. CE and WE must be LOW to initiate a write, and the transition of either of
these signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of t
