Abstract:
1. A nonvolatile memory device comprising: a first wiring line; a second wiring line disposed to cross the first wiring line; a variable resistive element having a resistance value, which is electrically rewritable in a high resistance state and in a low resistance state, and a non-ohmic element, the variable resistive element and the non-ohmic element being disposed at an intersection between the first wiring line and the second wiring line; and a control circuit configured to apply a first voltage to the variable resistive element, to apply a second voltage to the variable resistive element in a case where the resistance value of the variable resistive element, to which the first voltage has been applied, is greater than a resistance value of the low resistance state and is not greater than a resistance value of the high resistance state, and to repeat the applying of the second voltage to the variable resistive element until the resistance value of the variable resistive element, to which the second voltage has been applied, falls within a range of the resistance value of the low resistance state.
