1.5Gb (8-Meg X 48-Bit X 4-Banks) SDRAM
03.25.04 Rev 1
To [ACTV]: This command makes the other bank active. ( However, an interval of t
RRD is required.)
Attempting to make the currently active bank active results in an illegal command.
To [PRE], [PALL]: These commands set the SDRAM to precharge mode. (However, an interval of t
RAS is
required.)
From READ state, command operation
To [DESL], [NOP]: These commands continue read operations until the operation is completed.
To [READ], [READ A]: Data output by the previous read command continues to be output. After CAS
latency, the data output resulting from the next command will start.
To [WRIT], [WRIT A]: These commands stop a burst read, and start a write cycle.
To [ACTV]: This command makes other banks bank active. (However, an interval of t
RRD is required.)
Attempting to make the currently active bank active results in an illegal command.
To [PRE], [PALL]: These commands stop a burst read, and the SDRAM enters precharge mode.
From READ with AUTO-PRECHARGE state, command operation
To [DESL], [NOP]: These commands continue read operations until the burst operation is completed, and
the SDRAM then enters precharge mode.
To [ACTV]: This command makes other banks active. (However, an interval of t
RRD is required.) Attempting
to make the currently active bank active results in an illegal command.
From WRITE state, command operation
To [DESL], [NOP]: These commands continue write operations until the burst operation is completed.
To [READ], [READ A]: These commands stop a burst and start a read cycle.
To [WRIT], [WRIT A]: These commands stop a burst and start the next write cycle.
To [ACTV]: This command makes the other bank active. (However, an interval of t
RRD is required.)
Attempting to make the currently active bank active results in an illegal command.
To [PRE], [PALL]: These commands stop burst write and the SDRAM then enters precharge mode.
From WRITE with AUTO-PRECHARGE state, command operation
To [DESL], [NOP]: These commands continue write operations until the burst is completed, and the
synchronous DRAM enters precharge mode.
To [ACTV]: This command makes the other bank active. (However, an interval of t
RRD is required.)
Attempting to make the currently active bank active result in an illegal command.
From REFRESH state, command operation
To [DESL], [NOP]: After an auto-refresh cycle (after t
RC) the SDRAM automatically enters the IDLE state.
