Figure 42: Single Read – Without Auto Precharge
NOTE:
1. For this example, the burst length = 4, the CAS latency = 2, and the READ burst is followed by a “manual” PRECHARGE.
2. x16:A9 and A11 = “Don’t Care”
x32:A8, A9,and A11 = “Don’t Care”
3. PRECHARGE command not allowed or tRAS would be violated.
