AC Electrical Characteristics
(VDD = 1.8 ± 100mV, VDDQ = 1.4V to 1.9V, Commercial and Industrial Temperature Ranges)
NOTES:
1. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.
2. Vdd slew rate must be less than 0.1V DC per 50 ns for DLL lock retention. DLL lock time begins once Vdd and input clock are stable.
3. If C,C are tied High, K,K become the references for C,C timing parameters.
4. To avoid bus contention, at a given voltage and temperature tCHQX1 is bigger than tCHQZ.
5. This parameter is guaranteed by device characterization, but not production tested.
6. All address inputs must meet the specified setup and hold times for all latching clock edges.
7. During production testing, the case temperature equals TA.
8. Clock High Time (tKHKL) and Clock Low Time (tKLKH) should be within 40% to 60% of the cycle time (tKHKH).
9. Clock to Clock time (tKHKH) and Clock to Clock time (tKHKH) should be within 45% to 55% of the cycle time (tKHKH).
10. The 250MHz speed grade is not available in the 512K x 36-bit option.
11. Industrial temperature range is not available for the 250MHz speed grade.

The specs as shown do not imply bus contention because tCHQX1 is a MIN parameter that is worse case at totally different test conditions
It is not possible for two SRAMs on the same board to be at such different voltage and temperature.
(0°C, 1.9V) than tCHQZ, which is a MAX parameter (worst case at 70°C, 1.7V)
