Abstract

A nonvolatile semiconductor memory device includes a nonvolatile memory which includes a block having a plurality of memory cell groups, each of the memory cell groups being electrically connected to a plurality of bit lines and electrically connected to a common word line, each memory cell being recordable of a plurality of bits, a first register which stores information obtained by correcting first data to be written to a first word line, and a control circuit which sets a set potential in the first register and writes the bits to a write target first memory cell at a time using the information in the first register, the set potential being obtained by subtracting, from a target potential to be finally set in the first memory cell, a potential increase which is generated by setting a potential in an unwritten second memory cell adjacent to the first memory cell.
