Write enable truth table (per byte)
Key:
X = don’t care, L = low, H = high, n = a, b, c, d;
BWE
,
BWn
= internal write signal.
Asynchronous Truth Table
Notes:
1. X means “Don’t Care”
2. ZZ pin is pulled down internally
3. For write cycles that follows read cycles, the output buffers must be disabled with OE, otherwise data bus contention will occur.
4. Snooze mode means power down state of which stand-by current does not depend on cycle times
5. Deselected means power down state of which stand-by current depends on cycle times
