Abstract
A semiconductor memory device includes a substrate, a plurality of first conductive layers and a plurality of first insulating layers alternately arranged in a first direction intersecting the substrate, a first semiconductor layer extending in the first direction and facing the first semiconductor layers and the first insulating layers, a first charge storage layer disposed between the first conductive layers and the first semiconductor layer, and a second semiconductor layer connected to one end of the first semiconductor layer in the first direction. The first insulating layers at least partially contains a first element. The first element is at least one of phosphorus (P), arsenic (As), carbon (C), and argon (Ar).
