At any given temperature and voltage condition, t
is less than t
, t
is less than t
, and t
is less than t
for any given device.
t
, t
, and t
are specified with C
= 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage.
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.
The minimum write cycle time for write cycle #3 (WE controlled, OE LOW) is the sum of t
HZWE
and t
SD.
