Bank READ – with Auto Precharge
Notes:
1. NOP commands are shown for ease of illustration; other commands may be valid at these
times.
2. BL = 4.
3. The READ command can only be applied at T3 if tRAP is satisfied at T3.
4. Enable auto precharge.
5. tRP starts only after tRAS has been satisfied.
6. DO n = data-out from column n; subsequent elements are provided in the programmed
order.
