KM4132G271B

CMOS SGRAM

- 9 -

Rev. 2.4 (May 1998)

OPERATING AC PARAMETER

1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then

rounding off to the next higher integer.

2. Minimum delay is required to complete write.

3. This parameter means minimum CAS to CAS delay at block write cycle only.

4. In case of row precharge interrupt, auto precharge and read burst stop.

Note :

(AC operating conditions unless otherwise noted)
