Notes:

1. An initial pause of 200 µs is required after power-up followed by eight

RAS refresh cycles (RAS-Only or CBR) before proper device

operation is assured. The eight

2. Dependent on cycle rates.

3. Specified values are obtained with minimum cycle time and the output open.

4. Column-address is changed once each EDO page cycle.

5. Enables on-chip refresh and address counters.
