Abstract:
1. A nonvolatile semiconductor memory device, comprising a memory unit and a control unit, the memory unit including: the control unit performing a control of applying a first voltage to electrode portions adjacent to each other in one direction at different timing respectively when performing an erasing operation of performing at least one selected from injecting electron holes into the charge storage film and removing electrons from the charge storage film, the first voltage being applied from one of the electrode portions to the charge storage film to be erased; wherein the plurality of electrode portions are stacked with an interposed inter-electrode insulating film, and the charge storage film, the first insulating film, the second insulating film, and the semiconductor portion are provided in a hole piercing a structural body along a direction of the stacking, the structural body including the plurality of electrode portions stacked with the interposed inter-electrode insulating film.
