Abstract
The memory string comprises: a first semiconductor layer; a stacked body in which a plurality of conductive layers and a plurality of interlayer insulating layers are stacked along a first direction above the first semiconductor layer; and a second semiconductor layer having a longitudinal direction along the first direction and provided above the first semiconductor layer. The memory insulating layer includes a charge accumulation layer between the second semiconductor layer and the plurality of the conductive layers. The core insulating layer has a longitudinal direction along the first direction, and is provided in the second semiconductor layer. The oxide film layer is provided between the core insulating layer and the second semiconductor layer.
