PRELIMINARY
SNOOZE MODE
SNOOZE MODE is a low-current, “power-down”
mode in which the device is deselected and current is
reduced to I
SB
2
Z
. The duration of SNOOZE MODE is
dictated by the length of time ZZ is in a HIGH state.
After the device enters SNOOZE MODE, all inputs
except ZZ become gated inputs and are ignored.
ZZ is an asynchronous, active HIGH input that
causes the device to enter SNOOZE MODE. When ZZ
becomes a logic HIGH, I
SB
2
Z
is guaranteed after the
setup time
t
ZZ is met. Any READ or WRITE operation
pending when the device enters SNOOZE MODE is not
guaranteed to complete successfully. Therefore, SNOOZE
MODE must not be initiated until valid pending opera-
tions are completed.
