An electronic device of the present invention includes a memory core formed on an insulative substrate and implemented by a substance that performs, when a current flows therethrough, electromigration and varies in at least part of its shape or at least part of its element composition ratio. Two electrodes are directly bonded to opposite ends of the memory core. A sense electrode is spaced from the memory core by a thin insulative film in the vicinity of one of the two electrodes. A current flowing through the memory core causes a diffusion element to concentrate around either one of the two electrodes, whereby data is written in the memory core. Charge migration from the sense electrode caused by the migration of the diffusion element is sensed to thereby read the data out of the memory core. |
