GIn the framework of a large-scale project (NEUROTEC) including several collaborators from RWTH Aachen and Forschungszentrum Jülich we work on so-called reconfigurable devices as well as reconfigurable interconnect systems for a future implementation in neuromorphic hardware. Reconfigurable devices (RFETs) feature two or more gate electrodes that allow adjusting different functionalities of the devices; for example, an obvious extension is the reconfigurability enabling a device to work either as n-type or as p-type transistor. Moreover, combining such reconfigurable devices with memristive electro-chemical metallization (ECM) materials we explore the realization of a reconfigurable interconnect system. In such a system, interconnects are realized by growing a conductive filament through an ECM material in-between two electrodes actively controlled by RFETs. If the electrodes are arranged appropriately, interconnects can be realized in vertical and lateral directions enabling a three-dimensional interconnect system with very high connectivity for compute-in-memory applications.
