A Read command to the consecutive Write command interval with the BST command
Destination row of the consecutive write
command
Bank
address
Issue the BST command. tBSTW (
tBSTZ) after the BST command, the
consecutive write command can be issued.
Precharge the bank to interrupt the preceding read operation. tRP after the
precharge command, issue the ACT command. tRCD after the ACT command, the
consecutive write command can be issued. See ‘A read command to the
consecutive precharge interval’ section.
Issue the BST command. tBSTW (
tBSTZ) after the BST command, the
consecutive write command can be issued.
Precharge the bank independently of the preceding read operation. tRP after the
precharge command, issue the ACT command. tRCD after the ACT command, the
consecutive write command can be issued.
