SDRAM Read Cycles CAS Latency = 2 1. tRCD (delay time ACT to READ/WRITE command) = 30 ns or 2 cycles at 36 MHz. 2. tRP (PRE to ACT command period) = 30 ns or 2 cycles at 36 MHz. 3. tRAS (ACT to PRE command period) = 60 ns or 3 cycles at 36 MHz. 4. tRC (ACT to REF/ACT command period [operation]) = 90 ns or 4 cycles at 36 MHz. 5. For SDCAS latency 3, there will be an extra cycle between T4 and T5. 6. For CAS latency 3, there will be an extra cycle between T4 and T5.
