Notes: 1. DIn = data-out from column n; subsequent elements are provided in the programmed
order.
2. BL = 4 in the case shown.
3. Enable auto precharge.
4. ACT = ACTIVE, RA = Row Address, BA = Bank Address.
5. NOP commands are shown for ease of illustration; other commands may be valid at these
times.
6. See Figure 43 on page 81 for detailed DQ timing.
