Abstract
A semiconductor device includes a first conductive layer extending along a first direction, a semiconductor layer extending along a second direction crossing the first direction, penetrating the first conductive layer, and including an oxide semiconductor, a first insulating layer between the first conductive layer and the semiconductor layer, a second conductive layer provided on one side of the semiconductor layer in the second direction and electrically connected thereto, a third conductive layer provided on the other side of the semiconductor layer in the second direction and electrically connected thereto, an electric conductor extending from the third conductive layer toward the second conductive layer along the semiconductor layer, and a charge storage film between the semiconductor layer and the electric conductor.
