Method of writing data to the nonvolatile memory device and the nonvolatile memory device

A resistance variable layer changes: to a second resistance state in such a manner that its resistance value stops decreasing when an interelectrode voltage reaches a negative first voltage; to a first resistance state in such a manner that its resistance value starts increasing when the interelectrode voltage reaches a positive second voltage which is equal in absolute value to the first voltage; to the first resistance state in such a manner that the resistance variable layer flows an interelectrode current such that the interelectrode voltage is maintained at a third voltage higher than the second voltage, when the interelectrode voltage reaches the third voltage; and to the first resistance state in such a manner that its resistance value stops increasing when the interelectrode current reaches a first current in a state where the interelectrode voltage is not lower than the second voltage and lower than the third voltage.
