Abstract
A semiconductor storage device includes a stacked body in which conductive and insulating layers are alternately stacked in a first direction, conductive lines extending along a second direction intersecting the first direction and arranged along a third direction intersecting the first and second directions, insulators extending along the first and third directions in the body, arranged along the second direction, and dividing conductive layers, columnar bodies extending along the first direction and arranged along the second direction between insulators, each columnar body including a semiconductor body forming memory cells, and vias each connected between a conductive line and a corresponding columnar body. The conductive lines include first through fourth lines, and the columnar bodies include first through fourth bodies, arranged in this order. When viewed from the first direction, the first through fourth columnar bodies respectively overlap and are electrically connected to the first, third, second, and fourth lines.
