Abstract
A memory system includes: a bit counter and a regression analyzer. The bit counter is configured to generate a plurality of count values based on data read from selected memory cells using a plurality of different read voltages, each of the plurality of count values being indicative of a number of memory cells of a memory device having threshold voltages between pairs of the plurality of different read voltages. The regression analyzer is configured to determine read voltage for the selected memory cells based on the plurality of count values using regression analysis.
