A Read command to the consecutive Precharge command interval (same bank): To output all data
To complete a burst read operation and get a burst length of data, the consecutive precharge command must be
issued tRPD (= BL/ 2 cycles) after the read command is issued.

READ to PRECHARGE Command Interval (same bank): To output all data (CL = 3, BL = 4)
READ to PRECHARGE Command Interval (same bank): To stop output data
A burst data output can be interrupted with a precharge command. All DQ pins and DQS pins become High-Z tHZP
(= CL) after the precharge command.
