Abstract
According to one embodiment, this semiconductor memory device includes first conducting layers, a memory layer, and second conducting layers. The first conducting layers are laminated at predetermined pitches in a first direction perpendicular to a substrate. The first conducting layers extend in a second direction parallel to the substrate. The second conducting layer extends in the first direction. A memory layer surrounds a circumference of the second conductive layer. The first conductive layers is in contact with a side surface of the second conductive layer via the memory layer. The memory cells are provided at intersections of the first conducting layers and the second conducting layer.
