Abstract:
Multiple measurements are made with one memory sense operation having a first word line sensing voltage on a memory cell. The multiple measurements include a first measurement, of whether the memory cell stores either: (a) data corresponding to a first set of one or more threshold voltage ranges below the first word line sensing voltage of the one memory sense operation, or (b) data corresponding to a second set of one or more threshold voltage ranges above the first word line sensing voltage of the one memory sense operation. The multiple measurements include a second measurement, of error correction data of the memory cell indicating relative position within a particular threshold voltage range of a stored threshold voltage in the memory cell.
