Sleep Mode
The ZZ input pin is an asynchronous input. Asserting ZZ plac-
es the SRAM in a power conservation “sleep” mode. Two clock
cycles are required to enter into or exit from this “sleep” mode.
While in this mode, data integrity is guaranteed. Accesses
pending when entering the “sleep” mode are not considered
valid nor is the completion of the operation guaranteed. The
device must be deselected prior to entering the “sleep” mode.
