Notes:
1. When power is first applied, memory operation should be started 100 μs after Vdd and Vdd
Q
reach their stipulated voltages.
Also note that the power-on sequence must be executed before starting memory operation.
2. Measured with t
T
= 1 ns.
3. The reference level is 0.9V when measuring input signal timing. Rise and fall times are measured between V
IH
(min.) and V
IL
(max.).
4. Access time is measured at 0.9V with the load shown in the figure below.
5. The time t
HZ
(max.) is defined as the time required for the output voltage to transition by ± 200 mV from V
OH
(min.) or V
OL
(max.)
when the output is in the high impedance state.
