The minimum number of clocks from the burst write command to the burst read command is
(CL - 1) +BL/2 + tWTR
where tWTR is the write-to-read turn-around time tWTR expressed in clock cycles. The tWTR is not a write
recovery time (tWR) but the time required to transfer 4 bit write data from the input buffer into sense amplifiers
in the array.
