The following six items display the DRAM timing values. ► CAS Latency(Tcl) This item shows the CAS latency. The CAS Latency is the number of clock cycles that elapse from the time the request for data is sent to the actual memory location until the data is transmitted from the module. ► RAS / CAS Delay(Trcd) This item displays a delay time (in clock cycles) between the CAS and RAS strobe signals. ► Row Precharge Time(Trp) This item shows the number of clock cycles taken between issuing of the precharge command and the active command. The DRAM row precharge time is in unit of clock cycle. ► Min Active RAS(Tras) Displays the number of clock cycles taken between a bank active command and issuing of the precharge command. ► RAS / RAS Delay(Trrd) This item shows a delay time (in clock cycles) between the RAS and RAS strobe signals. ► Row Cycle(Trc) This item displays the minimum timing interval between successive active commands to the same bank. The row cycle time is in unit of clock cycle. ► OnChip VGA Frame Buffer Size Allocates system memory for use as video memory to ensure the most efficient use of avail- 26
