Abstract
According to one embodiment, a semiconductor memory device includes first and second memory cells, a word line, and first and second bit lines. The first and second bit lines are electrically connected to one ends of the first and second memory cells, respectively. In retry reading, a voltage applied to the first bit line is different from a voltage applied to the second bit line.
