Abstract
According to an embodiment, a non-volatile memory device includes a first conductive layer, electrodes, an interconnection layer and at least one semiconductor layer. The electrodes are arranged between the first conductive layer and the interconnection layer in a first direction perpendicular to the first conductive layer. The interconnection layer includes a first interconnection and a second interconnection. The semiconductor layer extends through the electrodes in the first direction, and is electrically connected to the first conductive layer and the first interconnection. The device further includes a memory film between each of the electrodes and the semiconductor layer, and a conductive body extending in the first direction. The conductive body electrically connects the first conductive layer and the second interconnection, and includes a first portion and a second portion connected to the second interconnection. The second portion has a width wider than the first portion.
