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. Both signals must be LOW to initiate a write and either signal can terminate
a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.
