Power Down (SNOOZE MODE)
Power Down or Snooze is a Power conservation mode which
when building large/very dense arrays, using multiple devices in a
multi-banked or paged array, can greatly reduce the Operating
current requirements of your total memory array solution.
The device is placed in this mode via the use of the ZZ pin, an
asynchronous control pin which when asserted, places the array
into the lower power or Power Down mode. Awakening the array
or leaving the Power Down (SNOOZE) mode is done so by de-
asserting the ZZ pin .
While in the Power Down or Snooze mode, Data integrity is
guaranteed. Accesses pending when the device entered the mode
are not considered valid nor is the completion of the operation
guaranteed. The device must be de-selected prior to entering the
Power Down mode, all Chip Enables, ADSP\ and ADSC\ must
remain inactive for the duration of ZZ recovery time (tZZREC).
