Patent ID: 8274821

Claim:
A nonvolatile memory device, comprising: a memory layer having a resistance changeable by performing at least one selected from applying an electric field and providing a current, the storage layer having a first major surface; a plurality of first electrodes provided on the first major surface; a plurality of probe electrodes disposed to face the plurality of first electrodes, the plurality of probe electrodes having a changeable relative positional relationship with the first electrodes; and a drive unit connected to the plurality of probe electrodes to record information in the memory layer by causing at least the one selected from the electric field and the current between at least two of the plurality of first electrodes via the plurality of probe electrodes, the electric field having a component parallel to the first major surface, the current flowing in a direction having a component parallel to the first major surface, wherein a first direction probe electrode pitch is a first direction electrode pitch multiplied by an integer, the first direction electrode pitch being a pitch between the plurality of first electrodes in a first direction parallel to the first major surface, the first direction probe electrode pitch being a pitch in the first direction between tips of each of the plurality of probe electrodes on a side facing the first electrodes.
