Patent ID: 7995374

Claim:
A nonvolatile semiconductor memory device, comprising a memory cell array including a memory cell, the memory cell being disposed between a first line and a second line and being configured by a variable resistor and a rectifier connected in series, the memory cell comprising: a variable resistance film configured to function as the variable resistor; a first conductive film having one surface contacted with one surface of the variable resistance film; a second conductive film having one surface contacted with another surface of the variable resistance film; and a rectifier layer having one surface contacted with another surface of the second conductive film and configured to function as the rectifier, a width of the first conductive film or the second conductive film in a direction orthogonal to a direction that a current flows in the first conductive film or the second conductive film being smaller than a width of the variable resistance film in a direction orthogonal to a direction that a current flows in the variable resistance film, and the width of the first conductive film and the second conductive film in the direction orthogonal to the direction that the current flows in the first conductive film and the second conductive film being smaller than a width of the first line and the second line in a direction orthogonal to a direction that a current flows in the first line and the second line.
