Notes:
1. AL = 0, RL = 8. 2. DO n (or b) = data-out from column n (or column b). 3. Seven subsequent elements of data-out appear in the programmed order following DO n. 4. Seven subsequent elements of data-out appear in the programmed order following DO b.

Notes:
1. NOP commands are shown for ease of illustration; other commands may be valid at these times. 2. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and A12 = 1 during the READ command at
T0, and the WRITE command at T6.
3. DO n = data-out from column, DI b = data-in for column b. 4. BL8, RL = 5 (AL = 0, CL = 5), WL = 5 (AL = 0, CWL = 5).
