Burst READ at End-of-Row (Wrap Off)
Notes:
t CLK
1. Nondefault BCR settings for burst READ at end of row: fixed or variable latency; WAIT
2. For burst READs, CE# must go HIGH before the third CLK after the WAIT period begins
output
Valid
active LOW; WAIT asserted during delay.
(before the third CLK after WAIT asserts with BCR[8] = 0 or before the fourth CLK after
WAIT asserts with BCR[8] = 1). Micron devices are fully compatible with the CellularRAM
Workgroup specification that requires CE# to go HIGH 1 cycle sooner than shown here.
