Precharge Timing During Read Operation
For the earliest possible Precharge command without interrupting a Read burst, the Precharge command
may be issued on the rising clock edge which is CAS latency (CL) clock cycles before the end of the Read
burst. A new Bank Activate (BA) command may be issued to the same bank after the RAS precharge time
(t
RP). A Precharge command can not be issued until tRAS(min) is satisfied.
