Abstract
A memory system includes a memory device including a plurality of memory cell transistors, and a memory controller. The memory controller is configured to write data to each of the plurality of memory cell transistors, the data having one of a plurality of bit values, read the data from the plurality of memory cell transistors, and measure a number of errors included in the read data with respect to two of the bit values of which corresponding threshold voltage distributions are adjacent to each other. The memory controller is further configured to adjust a difference between the threshold voltage distributions corresponding to the two of the bit values based on the measured number of errors.
