Abstract:
1. A nonvolatile storage device, comprising: a first conductive layer formed on a semiconductor substrate, and extended in a first direction along a main surface of the semiconductor substrate; a select element formed on the first conductive layer, and electrically connected to the first conductive layer; a stacked film including (N+1) (N is an integer of N≧1) first insulator films and N second conductive layers alternately stacked on the select element; a first semiconductor layer and a memory material layer which are formed on a sidewall of the stacked film through a second insulator film, and electrically connected to the select element; a third conductive layer formed on the stacked film, but not directly over the first semiconductor layer and the memory material layer in a stacking direction of the stacked film, and electrically connected to the first semiconductor layer; and a fourth conductive layer formed on the third conductive layer, electrically connected to the third conductive layer, and extended in a second direction orthogonal to the first direction.
