•
(Twr) Write Recovery Time (3 bus clocks)
: Use this item to specify the
Write to Read delay.
•
(Tcl) CAS# Latency (3)
: This item determines the operation of SDRAM memory
CAS(column address strobe). It is recommended that you leave this item at
the default value. The 2T setting requires faster memory that specifically
supports this mode.
•
(Trcd) RAS to CAS R/W Delay (6 clocks):
This is the amount of time a CAS
is performed after a RAS.The lower the better, but some DRAM does not
support low figures.
•
(Trrd) RAS toRAS Delay (6 clocks):
This item specifies the active-to-active
delay of different banks.
•
(Trp) Row Precharge Time (6 clocks)
: This item specifies the Row
precharge to Active or Auto-Refresh of the same bank.
•
(Tras) Minimum RAS active Time (18 bus clocks):
This item determines
the time RAS takes to read from and write to a memory cell.
•
(Trtp) Precharge Time (3 clocks)
: Use this item to specify the Precharge
Time.
•
(Trc) Row Cycle Time (26 bus clocks)
: Use this item to specify the Row
Cycle Time.
