Refresh Cycle Time (tRFC4) The number of clocks from a Refresh command until the first Activate command to the same rank. CAS Write Latency (tCWL) Configure CAS Write Latency. Read to Precharge (tRTP) The number of clocks that are inserted between a read command to a row precharge command to the same rank. Trdwr The minimum number of cycles from the last clock of virtual CAS of the first readburst operation to the clock in which CAS is asserted for a following write-burst operation. Twrrd The minimum number of cycles from the last clock of virtual CAS of the first write-burst operation to the clock in which CAS is asserted for a following read-burst operation.
