Abstract
According to one embodiment, a semiconductor memory device includes a substrate, a stacked body, a columnar section and an interconnection section. The stacked body includes a first insulating layer, a first electrode layer, a second insulating layer, and a second electrode layer. The first insulating layer includes a first surface facing the substrate, and a second surface facing the first electrode layer and opposite to the first surface. The second insulating layer includes a third surface facing the first electrode layer, and a fourth surface facing the second electrode layer and opposite to the third surface. A width of the interconnection section located between the first surface and the second surface in a second direction perpendicular to a stacking direction and a first direction is larger than a width of the interconnection section located between the third surface and the fourth surface in the second direction.
