AC CHARACTERISTICS
Symbol Parameter
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 t
3. The reference level is 1.4 V when measuring input signal timing. Rise and fall times are measured between V
4. Access time is measured at 1.4V with the load shown in the figure below.
5. The time t
output is in the high impedance state.
