Programmable CAS Latency: 5,6,7,8,9,10,11,13
Programmable Additive Latency(Posted CAS) : 0, CL - 2, or CL - 1 clock
Programmable CAS Write Latency(CWL) = 5 (DDR3-800), 6 (DDR3-1066), 7 (DDR3-1333), 8 (DDR3-1600) and 9 (DDR3-1866)
Burst Length: 8 (Interleave without any limit, sequential with starting address “000” only), 4 with tCCD = 4 which does not allow seamless read or
write [either On the fly using A12 or MRS]
