Abstract:
1. A nonvolatile memory device comprising: a storage element; a switching element electrically connected to the storage element; and a plurality of lead wirings electrically connected to the switching element or the storage element, all of which are arranged on a resin substrate, wherein the switching element is an organic transistor having an active layer composed of an organic semiconductor, and wherein the storage element contains an insulating thin film and is a storage element for storing information by changing a high resistance state to a low resistance state under insulation breakdown caused by voltage application, an impedance of the storage element being irreversibly changed to the low impedance state by applying a write voltage higher than a read voltage to the storage element, and wherein the storage element is a storage element comprising a first electrode, an insulating thin film provided on the first electrode, and a second electrode provided on the insulating thin film, and wherein at least one of the first electrode and the second electrodes is formed in a print processing of screen printing, offset printing, or micro contact printing.
