Notes:
1. The latency of CKE (l
CKE
) is one clock.
2. During read mode, burst counter will not be incremented/decremented at the next clock of CSUS command. Output
remain the same data.
3. During the write mode, data at the next clock of CSUS command is ignored.

Notes:
1. Precharge command (PRE or PALL) should be asserted if any bank is active and in the burst mode.
2. Precharge command can be posted in conjunction with CKE when burst mode is ended at this clock.
3. The ACTV command can be latched after t

(min) + 1 clock (min). It is recommended to apply NOP command in
conjunction with CKE. It is also recommended to apply minimum of 4 clocks to stabilize external clock prior to ACTV
command.
