Hybrid Devices for Neuromorphic Applications

Abstract

The world always seeks new materials, devices and technologies for a better future, and thus researchers keep exploring the possibilities. Advanced memory technology also aims to make the world better, comfortable, accessible and explorable. In this direction, hybrid devices consisting of dissimilar materials stacked or fused together can be considered as propitious. An attempt is made to identify the advantages of hybrid structures by implementing them into new memory technology architectures. Hybrid device structures including organic–inorganic, inorganic–inorganic (with different dimensions), an inorganic composite stacked between polymers, organic–perovskite, organic–organic and organic–biomolecule structures are discussed to showcase various memory related applications. The applications include digital memory, analog memory, multibit memory, and synapses. The neuromorphic application of these devices is also mentioned wherever possible. Some concepts like digital and analog memory, multibit memory and synapses are discussed elaborately. A crisp and easy way of understanding the neuromorphic application is presented in a schematic way for the comfort of the reader.
