1. Subsequent rising DQS signals must align to the clock within
2. DI b, etc. = data-in for column b, etc.
3. Three subsequent elements of data-in are applied in the programmed order following
4. Three subsequent elements of data-in are applied in the programmed order following
5. Shown with BL = 4, AL = 0, CL = 3; thus, WL = 2.
6. Each WRITE command may be to any bank.
