NOTE: 1. A write ends at the earlier transition of /CE going high and /WE going high.

2. A write occurs during the overlap of allow /CE and a low /WE. A write begins at the later transition of /CE

going low and /WE going low.

5. If /CE goes low simultaneously with /WE going low or after /WE going low, the outputs remain in high-

impedance state.
