Row active time
Row cycle time
Last data in to new col. Address delay
Last data in to row precharge
Last data in to burst stop
Col. Address to col. Address delay

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.
1. The minimum number of clock cycles is determined by dividing the minimum time required
The earliest a precharge command can be issued after a Read command without the loss of data is
CL + BL-2 clocks.
with clock cycle time and then rounding off to the next higher integer.
