Claim 17:
18. The non-volatile memory device of claim 16, wherein, to read the first page of hard bit data and corresponding first soft bit data, the one or more control circuits are configured to:
perform a hard bit read operation at a read level configured to determine a hard bit value for each of one or more selected non-volatile memory cells of the first page, the hard bit value indicating whether the memory cell is either reliably in a first data state or unreliability in a second data state; and
performing a soft bit read operation configured to generate a corresponding first soft bit value indicating a reliability value for each of the selected memory cells determined to be in the second data state, but not for memory cells determined to be in the first data state.
