SRAM Bus Signal Timing
1. Timing parameters assume that the system uses a zero delay clock buffer for SCLK before it is distributed to SRAM.
2. When used as a rdy input, HIGH_EN_L is asynchronous and can change anywhere relative to SCLK.
3. Capacitive loading effects on signal lines are shown in
4. T
5. Timings are what the tester must measure. Add 0.25 nsec to these numbers to obtain system AC parameter. This
6. Not tested. Guaranteed by design.

additional 0.25 nsec is needed to allow for SRAM drive derating.
