512-Mbit DDR2 SDRAM
Functional Description
3.23.2
Write with Auto-Precharge
If A10 is HIGH when a Write Command is issued, the
Write with Auto-Precharge function is engaged. The
DDR2 SDRAM automatically begins precharge
operation after the completion of the write burst plus the
write recovery time delay (WR), programmed in the
MRS register, as long as
t
RAS
is satisfied. The bank
undergoing Auto-Precharge from the completion of the
write burst may be reactivated if the following two
conditions are satisfied.
1. The last data-in to bank activate delay time (
t
DAL
=
WR +
t
RP
) has been satisfied.
2. The RAS cycle time (
t
RC
) from the previous bank
activation has been satisfied.
In DDR2 SDRAM’s the write recovery time delay (WR)
has to be programmed into the MRS mode register. As
long as the analog
t
WR
timing parameter is not violated,
WR can be programmed between 2 and 6 clock cycles.
Minimum Write to Activate command spacing to the
same bank = WL + BL/2 +
t
DAL
.
