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 fast page cycle.

5. Enables on-chip refresh and address counters.
