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 (BW2, BW3 for x36).
4. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.
5. V_DD slew rate must be less than 0.1 V DC per 50 ns for DLL lock retention. DLL lock time begins once V_DD and input clock are stable.
6. After device power-up, 20s of stable input clocks (as specified by t_KInit) must be supplied before reads and writes are issued.
