Abstract
According to one embodiment, a semiconductor memory device includes a substrate, a first signal line, a first conductive layer, a first storage layer and a first insulation layer. The first signal line extends in a first direction crossing the substrate. The first conductive layer extends in a second direction crossing the first direction and being parallel to the substrate, and has a first surface and a second surface that is away from the first signal line in a third direction crossing the first and second directions. The first storage layer is provided between the first signal line and the first conductive layer. The first insulation layer is provided between the second surface and the first storage layer.
