    A nonvolatile semiconductor memory includes a trench isolation provided in a semiconductor substrate and an interlayer insulator provided on the semiconductor substrate. The trench isolation defines an active area extending in a first direction at the semiconductor substrate. The interlayer insulator has a wiring trench extending in a second direction intersecting the first direction. A first conductive material layer is provided at the cross-point of the active area and the wiring trench so that it is insulated from the active area. A second conductive material layer is provided in the wiring trench so that it is insulated from the first conductive material layer. A metal layer is provided in the wiring trench so that it is electrically in contact the second conductive material layer.
