AC ELECTRICAL CHARACTERISTICS
Notes:
1. An initial pause of 100us is required after power up, followed by two AUTO REFRESH commands, before proper device opera-
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 that follows.
