1. 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 first read sense at a threshold voltage of one or more threshold voltages of each cell of a wordline of the plurality of wordlines;
determine that a second read sense is required based on the first read sense, wherein the second read sense comprises a plurality of left senses at a left threshold voltage and a plurality of right senses at a right threshold voltage;
determine a deviation parameter and a dispersion parameter for an asymmetric adjustment of the left threshold voltage and the right threshold voltage; and
adjust the left threshold voltage and the right threshold voltage based on the deviation parameter and the dispersion parameter.
