Patent ID: 7969789

Claim:
A method for driving a nonvolatile semiconductor memory device, the device having a stacked body in which insulating films and n (n is an integer of two or more) electrode films are alternately stacked and in which a through-hole extending in a stacking direction is formed, a semiconductor pillar buried inside the through-hole, and one pair of charge storage layers disposed in both sides of the electrode film in the stacking direction for each of the electrode films, the method comprising: giving relatively high potential to the electrode films of the number 1 to k (k is an integer of 1 to (n−1)) as counted from one end of the semiconductor pillar, giving relatively low potential to the electrode films of the number (k+1) to n, and therewith setting potential of the one end of the semiconductor pillar to be higher than potential of the other end, thereby injecting electrons into the charge storage layer on the other end side of one pair of the charge storage layers disposed on both sides of the electrode film of the number k.
