ABSTRACT:
A circuit for writing, reading, and erasing a programmable device is disclosed. The programmable device includes an ion conductor and a plurality of electrodes. Electrical properties of the device are altered by applying a sufficient bias across the electrode to form a conductive region within the ion conductor. The circuit can be used to program and read multiple bits within a single programmable device.
