A Write command to the consecutive Read command interval: To complete the burst operation
Destination row of the consecutive read
command
Bank
address
To complete the burst operation, the consecutive read command should be
performed tWRD (= BL/ 2 + 2) after the write command.
Precharge the bank tWPD after the preceding write command. tRP after the
precharge command, issue the ACT command. tRCD after the ACT command, the
consecutive read command can be issued. See ‘A read command to the
consecutive precharge interval’ section.
To complete a burst operation, the consecutive read command should be
performed tWRD (= BL/ 2 + 2) after the write command.
Precharge the bank independently of the preceding write operation. tRP after the
precharge command, issue the ACT command. tRCD after the ACT command, the
consecutive read command can be issued.
