The stacked body is provided on the substrate and includes a plurality of electrode layers separately stacked each other. A distance between the first columnar portion and one end of the plurality of electrode layers in the first direction is smaller than a distance between the second columnar portion and the other end of the plurality of electrode layers in the first direction. In the same electrode layer, a first width of a first charge storage film of the first columnar portion is smaller than a second width of a second charge storage film of the second columnar portion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device","description":"According to one embodiment, a semiconductor memory device includes a substrate; a stacked body; a first columnar portion; a second columnar portion; and a plurality of first interconnects.
