AC CHARACTERISTICS
Symbol Parameter
Notes:
1. When power is first applied, memory operation should be started 100 µs after V
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
