Abstract
A semiconductor memory device includes an interconnect layer including a conductive layer and a semiconductor layer of a first conductivity type provided on the conductive layer; a stacked body including a plurality of electrode layers stacked on the interconnect layer, a semiconductor pillar provided in the stacked body and extending through the plurality of electrode layers in a stacking direction thereof; and an insulating layer provided on the interconnect layer and extending along a lateral surface of the stacked body. The semiconductor layer includes a first semiconductor region of a second conductivity type positioned between the insulating layer and the conductive layer, and the first semiconductor region is in contact with the conductive layer.
