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 bank 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 results 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.
