The ZZ state is a low-power state in which the device consumes less power than in the unselected
mode. Enabling the ZZ pin for a fixed period of time will force the SRAM into the ZZ state. Pulling the
ZZ pin low for a set period of time will wake up the SRAM again. While the SRAM is in ZZ mode, data
retention is guaranteed, but the chip will not monitor any input signal except for the ZZ pin. In the
unselected mode, on the other hand, all the input signals are monitored.
