Organic- and Bio-Based Digital Memory Devices

Organic memory devices are considered as a viable approach for future information processing. We demonstrate this type of memory devices evolving from multiple layers structure to solution synthesis hybrid biomolecule structure. By forming a thin organic-nanoparticle layer or virus-nanoparticle layer in the crossbar junction, electronic memory effect based on electrical bistable states with a large on/off ratio, and long retention time is achieved. Temperature dependent data retention shows the nanoparticle formation determines the charge storage activation energy. Such organic, bio-inorganic nanostructures are promising for future memory technology.
