Abstract
According to one embodiment, a nonvolatile semiconductor memory device includes: a substrate; a memory unit provided on the substrate; and a non-memory unit provided on the substrate. The memory unit includes: a first stacked body including a plurality of first electrode films and a first inter-electrode insulating film, the plurality of first electrode films being stacked along a first axis perpendicular to the major surface, the first inter-electrode insulating film being provided between two of the first electrode films mutually adjacent along the first axis; a first semiconductor layer opposing side surfaces of the first electrode films; a first memory film provided between the first semiconductor layer and the first electrode films; and a first conductive film provided on the first stacked body apart from the first stacked body. The non-memory unit includes a resistance element unit of the same layer as the conductive film.
