SINGLE WRITE - WITHOUT AUTO PRECHARGE1

*CAS latency indicated in parentheses.

NOTES:

1. For this example, the burst length = 1, and the WRITE burst is followed by a “manual” PRECHARGE.

2. 14ns to 15ns is required between <D

IN m> and the PRECHARGE command, regardless of frequency. With a single write tWR has been increased to meet

minimum t

RAS requirement.

3. A9, A11, and A12 = “Don’t Care”

4. PRECHARGE command not allowed else t

RAS would be violated.
