3. These parameters are guaranteed but not tested.
4. WE must be HIGH during SRAM Read Cycles.
5. Device is continuously selected with CE and OE both Low.
6. Measured ±200 mV from steady state output voltage.
7. If WE is Low when CE goes Low, the outputs remain in the high impedance state.
8. t
9. If an SRAM Write does not take place since the last nonvolatile cycle, no STORE takes place.
