1.25Gb (8-Meg X 40-Bit X 4-Banks) SDRAM
05.10.06 Rev 4
From PRECHARGE state, command operation
To [DESL], [NOP]: When these commands are executed, the SDRAM enters the IDLE state after t
RP has
elapsed from the completion of precharge.
From IDLE state, command operation
To [DESL], [NOP], [PRE], or [PALL]: These commands result in no operation.
To [ACTV]: The bank specified by the address pins and the ROW address is activated.
To [REF], [SELF]: The SDRAM enters refresh mode (auto-refresh or self-refresh).
To [MRS]: The synchronous DRAM enters the mode register set cycle.
From ROW ACTIVE state, command operation
To [DESL], [NOP]: These commands result in no operation.
To [READ], [READ A]: A read operation starts. (However, an interval of t
RCD is required.)
To [WRIT], [WRIT A]: A write operation starts. (However, an interval of t
RCD is required.)
