Abstract

Disclosed are a semiconductor storage device and a manufacturing method. The storage device has: a substrate; a first word line above the substrate; a first laminated body above the first word line and having N+1 first inter-gate insulating layers and N first semiconductor layers alternately laminated; a first bit line above the laminated body and extending in a direction that intersects the first word line; a first gate insulating layer on side surfaces of the first inter-gate insulating layers and the first semiconductor layers; a first channel layer on the side surface of the first gate insulating layer; and a first variable resistance material layer on the side surface of the first channel layer. The first variable resistance material layer is in a region where the first word line and the first bit line intersect. A polysilicon diode is used as a selection element.
