Notes:
1. When power is first applied, memory operation should be started 100 µs after Vcc and VccQ reach their stipulated
voltages. Also note that the power-on sequence must be executed before starting memory operation.
2. Measured with tT = 1 ns.
3. The reference level is 1.4 V when measuring input signal timing. Rise and fall times are measured between VIH (min.) and
VIL (max.).
4. Access time is measured at 1.4V with the load shown in the figure below.
5. The time tHZ (max.) is defined as the time required for the output voltage to transition by ± 200 mV from VOH (min.) or VOL
(max.) when the output is in the high impedance state.
