An initial pause of 200
μ
s, with DQMB0-7 and CKE0-CKE1 held high, is required after power-up. A Precharge All Banks command must
be given followed by a minimum of eight Auto (CBR) Refresh cycles before or after the Mode Register Set operation.
1. The Transition time is measured between V
IH
and V
IL
(or between V
IL
and V
IH
).
2. In addition to meeting the transition rate specification, the clock and CKE must transit between V
IH
and V
IL
(or between V
IL
and V
IH
)
in a monotonic manner.
3. Load Circuit: AC timing tests have V
IL
= 0.8 V and V
IH
= 2.0 V with the timing referenced to the 1.40V crossover point
4. Load Circuit: AC measurements assume t
T
=1.2ns.
