1. DO an = data-out from bank a and address n.
2. DI bn = data-in for bank b and address n.

Transitioning Data
Don’t Care
1. DO n = data-out from bank a and address n.
2. Represents DQs associated with a specific QK, QK# pair.
Notes:
3. Output timings are referenced to VDDQ/2 and DLL on and locked.
4. tQKQx defines the skew between the QK0, QK0# pair to its respective DQs. tQKQx does
not define the skew between QK and CK.
5. Early data transitions may not always happen at the same DQ. Data transitions of a DQ
can vary (either early or late) within a burst.
