Superconducting memristors for memory and neuromorphic applications

The concept we aim a proving is a novel type of electronic device, a redox superconducting memristor, whose functionality is beyond that of binary memories: it shows a continuum of states (instead of just two), and the switching between them can be driven by a sequence of voltage pulses or by visible light illumination.

Furthermore, it is based on high-temperature superconductors, allowing for low-dissipation devices.

This concept stems from recent work in the frame of an ERC consolidator grant, which has demonstrated the physical mechanism that produces the memristive behavior: a controlled red-ox reaction.

The structural simplicity of the proposed memristor radically improves scalability and facilitates fabrication as compared to the existing approaches.

The new functionalities it brings, particularly photosensitivity and the superconductivity, open new avenues in the areas of application, which include neuromorphic computing and superconducting electronics.
