Abstract
A semiconductor memory device comprises: a first memory layer; and a first via wiring and a second via wiring extending in a first direction, and having different positions from each other in a second direction. The first memory layer comprises: a first transistor electrically connected to the first via wiring; a memory portion electrically connected to the first transistor; a first wiring electrically connected to the first transistor; a second transistor electrically connected to the second via wiring and the first wiring; a first electrode electrically connected to the second transistor; and a second electrode electrically connected to the first wiring and first electrode. A length of the second electrode in the first direction is larger than one or both of a length of the first wiring in the first direction and a length of the first conductive layer in the first direction.
