internally to the DDR3 SDRAM device. READ latency (RL) is controlled by the sum of
the AL and CAS latency (CL), RL = AL + CL. WRITE latency (WL) is the sum of CAS
WRITE latency and AL, WL = AL + CWL (see Mode Register 2 (MR2) (page 141)). Exam-
ples of READ and WRITE latencies are shown in Figure 55 (page 140) and Figure 56
(page 141).
