Row Precharge Time(tRP) 9
RAS# Active Time(tRAS) 2 4
Write Recovery Time(tWR) 1 0
Row Refresh Cycle Time(tRFC) 74
Active to Active Delay(tRRD) 4
Write to Read Delay(tWTR) 5
Read CAS# Precharge(tRTP) 5
Four Active Window Delay(tFAW) 20
CAS# Latency(tCL) (7)
This item determines the operation of DDR 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.
Row Precharge Time(tRP) (7)
This item specifies Row precharge to Active or Auto-Refresh of the same bank.
RAS# to CAS# Delay(tRCD) (7)
This item specifies RAS# to CAS# delay to Rd/Wr command to the same bank.
RAS# Active Time(tRAS) (20)
This item specifies the RAS# active time.
Write Recovery Time(tWR) (8)
This item specifies the write recovery time.
Row Refresh Cycle Time(tRFC) (59)
This item specifies the row refresh cycle time.
Write to Read Delay(tWTR) (4)
This item specifies the write to read delay time.
Active to Active Delay(tRRD) (4)
This item controls the active bank x to active bank y in memory clock cycles.
Read CAS# Precharge(tRTP) (4)
This item controls the Read to precharge delay for memory devices, in memory clock
cycles.
