Original Abstract Submitted
A semiconductor memory device includes: a memory cell array including a plurality of bit lines, a source line, a plurality of NAND strings, a first and a second sub block, a first word line group included in the first sub block, a second word line group included in the second sub block, and a dummy word line located between the first and second sub blocks; and a control circuit capable of applying predetermined voltages to the first word line group, the second word line group, and the dummy word line. When a specific word line belonging to the first word line group is selected for the execution of a write operation, a voltage higher than voltages applied to an unselected word line belonging to the first word line group and the second word line group is applied to the dummy word line.
