AC OPERATING TEST CONDITIONS
OPERATING AC PARAMETER
(AC operating conditions unless otherwise noted)
Note: 1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and

5. A new command may be given t
2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.
6. A maximum of eight consecutive AUTO REFRESH commands (with t
then rounding off to the next higher integer.
The earliest a precharge command can be issued after a Read command without the loss of data is CL+BL-2 clocks
the maximum absolute interval between any AUTO REFRESH command and the next AUTO REFRESH command is
8x15.6μs.)
