Abstract
A semiconductor structure is provided that contains a non-volatile battery which controls gate bias. The non-volatile battery has a stable voltage and thus the structure may be used in neuromorphic computing. The semiconductor structure may include a semiconductor substrate including at least one channel region that is positioned between source/drain regions. A gate dielectric material is located on the channel region of the semiconductor substrate. A battery stack is located on the gate dielectric material. In accordance with the present application, the battery stack includes, an anode current collector located on the gate dielectric material, an anode region located on the anode current collector, an ion diffusion barrier material located on the anode region, an electrolyte located on the ion diffusion barrier material, a cathode material located on the electrolyte, and a cathode current collector located on the cathode material.
