Asymmetric read sense

A data storage device, comprising:

• a memory device comprising a plurality of wordlines, each comprising a plurality of cells;
• and
• a cell statistics generator (CSG) disposed on the memory device, the CSG comprising logic configured to:
• receive a plurality of left read senses and a plurality of right read senses for a threshold voltage of a plurality of threshold voltages for each cell of the plurality of cells of a wordline of the plurality of wordlines;
• sum a plurality of received left read senses and a plurality of right read senses, wherein an expectation value is subtracted from the summed plurality of received left read senses and the summed plurality of right read senses;
• calculate a deviation parameter and a dispersion parameter;
• and
• asymmetrically adjust the plurality of left read senses and the plurality of right read senses based on the deviation parameter and the dispersion parameter.

A data storage device, comprising:

• memory means comprising a plurality of wordlines, each comprising a plurality of cells;
• and
• one or more cell statistics generators (CSGs) disposed on the memory means, the one or more CSGs each comprising logic configured to:
• receive a plurality of left read senses at a first voltage from a threshold voltage of each cell of a wordline of the plurality of wordlines, wherein the first voltage is substantially less than the threshold voltage;
• receive a plurality of right read senses at a second voltage from the threshold voltage, wherein the second voltage is substantially greater than the threshold voltage, and wherein the first voltage and the second voltage are offset by a substantially equal voltage from the threshold voltage;
• determine a deviation parameter and a dispersion parameter to asymmetrically adjust the first voltage and the second voltage;
• and
• adjust the first voltage and the second voltage based on the deviation parameter and the dispersion parameter.
