Claim 13:
14. The method of claim 13, further comprising:
prior to performing the first sensing operation, biasing the on non-volatile memory cells at a first voltage level and pre-charging, for each of the non-volatile memory cells, a corresponding sense node to a first level, wherein performing the first sensing operation for each of the non-volatile memory cells includes:
discharging the corresponding sense node pre-charged to the first level through the memory cell biased at the first voltage level for a first sensing interval; and
distinguishing between the first data state and the second data state based on an amount that the sense node discharges during the first sensing interval, and

wherein the performing the second sensing operation for each of the non-volatile memory cells determined to be in the second data state includes:
continuing to discharge the corresponding sense node pre-charged to the first level through the memory cell biased at the first voltage level for a first additional sensing interval; and
determining the reliability of the first sensing based on an amount that the sense node discharges during the combined first sensing interval and first additional sensing interval.
