... The accesses are enabled with the chip select signals and output enabled signals. Wait states are inserted into the access with ADV. When ZZ is pulled high, the SRAM will enter a Power Down State. At this time, internal state of the SRAM is preserved. When ZZ returns to low, the SRAM normally operates after 2cycles of wake up time. ZZ pin is pulled down internally. ...
