Data Retention Waveform
Notes:
6. 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
/I
and transmission line loads. Test conditions for the read cycle use output loading as shown in (a) of AC Test Loads, unless specified otherwise.
7. This part has a voltage regulator that steps down the voltage from 3V to 2V internally. t
time has to be provided initially before a read/write operation is started.
8. t

are specified with a load capacitance of 5 pF as in (b) of AC Test Loads. Transition is measured
± 200 mV from steady-state voltage.
9. These parameters are guaranteed by design and are not tested.
10.The internal write time of the memory is defined by the overlap of CE
LOW, CE
HIGH, CE
LOW, and WE LOW. The chip enables must be active and WE
must be LOW to initiate a 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.
11. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of t
HZWE
and t
