AC ELECTRICAL CHARACTERISTICS
Notes:
1. An initial pause of 100us is required after power up, followed by two AUTO REFRESH commands, before proper device
2. Measured with t
3. The reference level is 1.5V when measuring input signal timing. Rise/fall times are measured between V
4. Access time is measured at 1.5V with the load shown in the figure below.
5. The time t
6. CLK must be toggled a minimum of two times during this period.
