Notes:
1. All Address inputs must meet the specified setup and hold times for all latching clock edges.
2. Control signals are R, W
3. Control signals are BW0, BW1, and (NW0, NW1 for x8) and (BW2, BW3 for x36).
4. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.
5. VDD slew rate must be less than 0.1 V DC per 50 ns for DLL lock retention. DLL lock time begins once VDD and input clock are stable.
