1. DI n (or b) = data-in for column n (or column b).
2. Seven subsequent elements of data-in are applied in the programmed order following DO n.
3. Each WRITE command may be to any bank.
4. Shown for WL = 7 (CWL = 7, AL = 0).
1. NOP commands are shown for ease of illustration; other commands may be valid at these times.
2.
3. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and MR0[12] = 1 during the WRITE command at T0.
4. DI n = data-in for column n.
5. RL = 5 (AL = 0, CL = 5), WL = 5 (AL = 0, CWL = 5).
t
data shown at T9.
The READ command at Ta0 can be either BC4 or BL8, depending on MR0[1:0] and the A12 status at Ta0.
WTR controls the WRITE-to-READ delay to the same device and starts with the first rising clock edge after the last write
WL = CWL + AL = 7
