Abstract
An optoelectronic memory cell has a transparent top electrode, a photoactive layer, a latching layer, and a bottom electrode. The photoactive layer absorbs photons transmitted through the top electrode and generates charge carriers. During light exposure, the latching layer changes its resistance under an applied electric field in response to the generation of charge carriers in the photoactive layer.
