Abstract
Charge storage and sensing devices having a tunnel diode operable to sense charges stored in a charge storage structure are provided. In some embodiments, a device includes a substrate, a charge storage device on the substrate, and tunnel diode on the substrate adjacent to the charge storage device. The tunnel diode includes a tunnel diode dielectric layer on the substrate, and a tunnel diode electrode on the tunnel diode dielectric layer. A substrate electrode is disposed on the doped region of the substrate, and the tunnel diode electrode is positioned between the charge storage device and the substrate electrode.
