CAS Latency(CL)

When the DRAM Timing Mode sets to [Manual], the field is adjustable.This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it.

Advance DRAM Configuration -> tRCD

When the DRAM Timing Mode sets to [Manual], the field is adjustable. When DRAM is refreshed, both rows and columns are addressed separately. This setup item allows you to determine the timing of the transition from RAS (row address strobe) to CAS (column address strobe). The less the clock cycles, the faster the DRAM performance.

Advance DRAM Configuration -> tRP

When the DRAM Timing Mode sets to [Manual], this field is adjustable. This setting controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refresh may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system.

Advance DRAM Configuration -> tRAS

When the DRAM Timing Mode sets to [Manual], this setting determines the time RAS takes to read from and write to a memory cell.

Advance DRAM Configuration -> tRTP

When the DRAM Timing Mode sets to [Manual], this setting controls the time interval between a read and a precharge command.

Advance DRAM Configuration -> tRC

When the DRAM Timing Mode sets to [Manual], the field is adjustable. The row cycle time determines the minimum number of clock cycles a memory row takes to complete a full cycle, from row activation up to the precharging of the active row.

Advance DRAM Configuration -> tWR

When the DRAM Timing Mode sets to [Manual], the field is adjustable. It speci- fies the amount of delay (in clock cycles) that must elapse after the completion of a valid write operation, before an active bank can be precharged. This delay is required to guarantee that data in the write buffers can be written to the memory cells before precharge occurs.

Advance DRAM Configuration -> tRRD

When the DRAM Timing Mode sets to [Manual], the field is adjustable. Speci- fies the active-to-active delay of different banks.

Advance DRAM Configuration -> tWTR

When the DRAM Timing Mode sets to [Manual], the field is adjustable. This item controls the Write Data In to Read Command Delay memory timing. This
