Equivalent to:
5. 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

7. At any given temperature and voltage condition, t
8. The internal write time of the memory is defined by the overlap of CE
9. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of t

write, and the transition of any 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.
