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
RAS
cycles wake-up should be repeated any time the t
REF
refresh requirement is exceeded.
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.
6. I
CCS
is for S version only.
