Claim 15:
16. A method, comprising:
applying, to sense respective data states of memory cells of a group of first memory cells of a memory, a first voltage pulse to the group of first memory cells, wherein the memory further comprises one or more second memory cells whose data state is indicative of whether to refresh the group of first memory cells;
applying, to sense a data state of one or more second memory cells, a second voltage pulse having a greater magnitude than the first voltage pulse to the one or more second memory cells, while the first voltage pulse is applied to the group of first memory cells; and
selectively refreshing, in response to the sensed data state of the one or more second memory cells being different from a particular data state to which the one or more second memory cells was previously programmed, those memory cells of the group that did not experience a snapback event in response to the first voltage pulse being applied.
