Abstract
According to one embodiment, a memory system includes a decoder configured to correct an error of the data stored in a memory based on result of the first read and the second read, and output a first signal of a first value indicating corrected data and a second signal of a second value indicating corrected data; a generator configured to count the first and second signals for first data items based on the result of the first and second read for generating count numbers of the first and second signals for each of the first data items; and a controller configured to compare a magnitude relation of the count numbers in order of read levels, determine the first data item when the magnitude relation changes.
