8. 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 any of these
I
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.
