Abstract
A method for operating a data storage device includes determining appropriateness of a first read bias for adjacent target threshold voltage distributions among threshold voltage distributions for a plurality of memory cells; and if it is determined that the first read bias is inappropriate, determining a second read bias.

A method for operating a data storage device, comprising:
- determining appropriateness of a first read bias for adjacent target threshold voltage distributions among threshold voltage distributions for a plurality of memory cells;
- and
- if it is determined that the first read bias is inappropriate, determining a second read bias.
A method for operating a data storage device, comprising:
- determining appropriateness of a first read bias for adjacent target threshold voltage distributions among threshold voltage distributions for a plurality of memory cells;
- if it is determined that the first read bias is inappropriate, determining a start bias corresponding to the target threshold voltage distributions, based on a Gaussian modeling algorithm and an error rate of the first read bias;
- and
- determining a second read bias based on the start bias.
