02.04.05 Rev 3
From PRECHARGE state, command operation
To [DESL], [NOP]:
When these commands are executed, the SDRAMenters the IDLE state after t
RP
has
elapsed fromthe 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 DRAMenters 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.)
