Abstract
A non-volatile memory device includes a plurality of wordlines, each comprising a plurality of cells, a hard decode configured to read each cell of the plurality of cells at a hard decode voltage, a left read sense configured to read voltage values of each cell to the left of the hard decode voltage at a left read sense voltage, a right read sense configured to read voltage values of each cell to the right of the hard decode voltage at a right read sense voltage, a first combiner configured to determine a difference of voltage values read by the left read sense and right read sense to produce a dispersion signal, and a second combiner configured to determine a sum of the voltage values read by the left read sense and right read sense to produce a deviation signal.
