From WRITE state, command operation
To [DESL], [NOP]:
These commands continue write operations until the burst operation is completed.
To [BST]:
This command stops a full-page burst.
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.) At-
tempting to make the currently active bank active results in an illegal command.
To [PRE], [PALL]:
These commands stop burst write and the SDRAM module 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
SDRAM module enters precharge mode.
To [ACTV]:
This command makes the other bank active. (However, an interval of t
RRD
is required.) At-
tempting to make the currently active bank active results in an illegal command.
From REFRESH state, command operation
To [DESL], [NOP], [BST]:
After an auto-refresh cycle (after t
RC
), the SDRAM module automatically enters
the IDLE state.
