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. Setting options: [Auto], [2T], [3T], [4T], [5T], [6T], [7T]. Row Precharge Time (Trp) When the Timing Mode is set to [Manual], the field is adjustable. This item 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, refreshing may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system. Available settings: [Auto], [2T], [3T], [4T], [5T], [6T], [7T]. Row cycle time (Trc) When the Timing Mode is set 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.

Available settings: [Auto], [2T], [3T], [4T]. Write recovery time (Twr) When the Timing Mode is set to [Manual], the field is adjustable. It specifies 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. Available settings: [Auto], [2T], [3T]. Write to Read delay (Twtr) When the Timing Mode is set to [Manual], the field is adjustable. This item controls the Write Data In to Read Command Delay memory timing. This consti- tutes the minimum number of clock cycles that must occur between the last valid write operation and the next read command to the same internal bank of the DDR device. Available settings: [Auto], [1T], [2T]. Read to Write delay (Trwt) When the Timing Mode is set to [Manual], the field is adjustable. This is not a DRAM-specified timing parameter, but must be considered due to routing laten- cies on the clock forwarded bus. It is counted from the first address bus slot that was not associated with part of the read burst. Available settings: [Auto], [1T], [2T], [3T], [4T], [5T], [6T].
