Read With Auto Precharge
If a read with auto-precharge command is initiated, the DDR SDRAM automatically enters the precharge operation BL/2 clock
later from a read with auto-precharge command when t
RAS
(min) is satisfied. If not, the start point of precharge operation will be
delayed until t
RAS
(min) is satisfied. Once the precharge operation has started the bank cannot be reactivated and the new
command can not be asserted until the precharge time (t
RP
) has been satisfied
