1. NOP commands are shown for ease of illustration; other commands may be valid at these times.
Notes:
2. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and A12 = 1 during READ command at T0
and T4.
3. DO n (or b) = data-out from column n (or column b).
4. BL8, RL = 5 (CL = 5, AL = 0).
