Abstract
A device includes a stack above a substrate in a first direction perpendicular to a surface of the substrate, the stack including conductive layers; a semiconductor layer neighboring the stack in a second direction parallel to the surface of the substrate; a memory layer between the first stack and the semiconductor layer; memory cells between the conductive layers and the semiconductor layer; a first transistor connected between one end of the semiconductor layer in a third direction parallel to the surface of the substrate and crossing the second direction and a first interconnect in the first direction; and a second transistor connected between the other end of the semiconductor layer and a second interconnect in the first direction.
