Patent ID: 8541866

Claim:
A nonvolatile semiconductor memory device, comprising: a stacked structural unit including a plurality of stacked component units stacked in a first direction, each of the stacked component units including a first conducting film and a first insulating film stacked with the first conducting film in the first direction, the first conducting film being provided in a plane perpendicular to the first direction and made of a semiconductor of a first conductivity type; a semiconductor pillar piercing the stacked structural unit in the first direction and including a conducting region of a second conductivity type, the semiconductor pillar including first regions, each of the first regions being provided in the plane with each of the first conducting films, the first regions being apart from each other in the first direction, and a second region provided between the first regions with respect to the first direction, the second region having a resistance different from a resistance of each of the first regions; and memory portions including a second insulating film, each of the memory portions being provided between each of the first regions and the first conducting film, the second insulating film being provided between the semiconductor pillar and the first conducting film.
