• Manufacturer: Samsung Semiconductor, Inc.

K4M51323PC-S(D)E/G/C/F
OPERATING AC PARAMETER
(AC operating conditions unless otherwise noted)
NOTES:
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
2. Minimum delay is required to complete write.
3. Maximum burst refresh cycle : 8
4. All parts allow every cycle column address change.
5. In case of row precharge interrupt, auto precharge and read burst stop.
