1. An initial pause of 100µs is required after power-up, then a Precharge All Banks command must be given followed by a minimum of
two Auto (CBR) Refresh cycles before the Mode Register Set operation can begin.
2. The Transition time is measured between VIH and VIL (or between VIL and VIH).
3. In addition to meeting the transition rate specification, the clock and CKE must transit between VIH and VIL (or between VIL and VIH)
in a monotonic manner.
4. AC timing tests have VIL = 0.4 V and VIH = 2.4 V with the timing referenced to the 1.40V crossover point.
5. AC measurements assume tT=1.0 ns.

1. Access time is measured at 1.4V. See AC Characteristics: notes 1,2,3,4,5 and load circuit.
2. Access time is measured assuming a clock rise time of 1 ns. If clock rise time is longer than 1 ns, then (trise/2-0.5)ns should be
added to the parameter.
3. Assumes clock rise and fall times are equal to 1 ns. If rise or fall time exceeds 1 ns, then other AC parameters under consider-
ation should be compensated by an additional [(trise+tfall)/2-1]ns.
