Patent ID: 7027327

Claim:
A nonvolatile memory comprising: at least a first electrode and a second electrode provided on a substrate, the first and second electrodes being separated from each other; and a conductive organic thin film for electrically connecting the first and second electrodes, wherein the conductive organic thin film has a first electric state in which it exhibits a first resistance, and a second electric state in which it exhibits a second resistance, a first threshold voltage for a transition from the first electric state to the second electric state, and a second threshold voltage for a transition from the second electric state to the first electric state are different from each other, either the first electric state or the second electric state is maintained at a voltage in a range between the first threshold voltage and the second threshold voltage, the conductive organic thin film is formed with organic molecules, each of which includes: a terminal binding group that is bound with a surface of the substrate or a surface of an insulation layer on the substrate by a covalent bond; and a conjugate group, and, each conjugate group is polymerized with another conjugate group of another organic molecule so as to form the conductive organic thin film.
