NONVOLATILE SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory device which can improve operation reliability.SOLUTION: The nonvolatile semiconductor memory device includes a first memory cell connected to a first word line WL0, and a second memory cell connected to a second word line WL1 adjacent to the first word line and different in width from the first memory cell. A first voltage is applied to the first word line, and a second voltage different from the first voltage and corrected based on a difference in width between the first memory cell and the second memory cell is applied to the second word line.
