Abstract
According to one embodiment, a semiconductor memory device includes a first interconnect layer, a first insulating layer, a second interconnect layer, and a memory pillar including a second insulating layer, a charge storage layer, and a third insulating layer stacked on a part of a side surface and on the bottom surface of the memory pillar, and a first silicide layer in contact with the first interconnect layer, a semiconductor layer, and a second silicide layer stacked in order along a first direction. A height position of a bottom surface of the first silicide layer is lower than a top surface of the first interconnect layer, and a height position of a top surface of the first silicide layer is higher than a bottom surface of the second interconnect layer.
