Active to CMD(Trcd)
2T
3T
4T
5T
This timing controls the length of the delay
between when a memory bank is activated to
when a read/write command is sent to that bank.
REF to ACT/REF to REF(Trfc) 08T, 09T…~70T, 71T
Set the REF to ACT/REF to REF timing.
This field appears when DRAM Timing is set at
Manual
.
ACT(0) to ACT(1) (TRRD)
2T
3T
4T
5T Set the minimum time interval between
successive ACTIVE commands to the different
banks. This field appears when DRAM Timing is
set at Manual.
Read to Precharge (Trtp)
2T
3T
This bits control the number of clocks that are
inserted between a read command to a row
precharge command to the same rank.
Writ to Read CMD (Twtr)
1T/2T
2T/3T
Allows to set the Write to Read CMD function.
Write Recovery Time (Twr)
2T
3T
4T
5T
Write recovery time is a standard DDR2 timing
parameter minimum time between a write
command
and subsequent prechanrge
command to the same bank. The parameter is
programmable on DDR2 SODIMMs and the
value used above must match the largest delay
programmed in any SODIMM in the system.
DRAM Command Rate
2T Command
1T Command
Allows to set the DRAM Command Rate.
RDSAIT Mode
Manual
Auto
Allows to select RSDAIT Mode.
RDSAIT Selection 3 Allows to set RSDAIT selectiion.
