Accuracy of sensing operations, such as read or verify, in a memory device
is improved by avoiding fluctuations in a sense amp supply voltage which
can occur when different sense amps are strobed at different times. First
and second sets of sense amps perform a sensing operation on respective
storage elements, such as in an all bit line configuration. The first set
of sense amps is strobed at a first time point. In response, a sensed
analog level is converted to digital data. The A/D conversion relies on
the sense amp supply voltage being accurate. To avoid a fluctuation in
the sense amp supply voltage, a bypass path allows the storage elements
associated with the first set of sense amps to continue to draw power
from the sense amp supply voltage. The second set of sense amps is
strobed at a later, second time point.
