Abstract:
According to one embodiment, a nonvolatile semiconductor memory device includes a memory cell array and a control circuit. The memory cell array include the memory cells each including a variable resistance element in which a reset current flowing in a reset operation is smaller than a set current flowing in a set operation by not less than one order of magnitude. The control circuit performs the reset operation and the set operation for the memory cells. The control circuit performs the reset operation for all memory cells being in the low resistance state and connected to selected first interconnections and selected second interconnections.
