About us

The Cognitive Systems (CoSy) Group main research interests rely at the intersection of emerging memory devices, circuit design, and brain-inspired computing. We use design-technology co-optimisation (DTCO) of emerging memory devices and CMOS circuits to enable seamless integration and to exploit the strengths of both technologies. More specifically, we focus on extending the functionality of CMOS circuits by leveraging the intrinsic physical characteristics of emerging memory devices to design advanced cognitive systems. The group was established on January 1st, 2024 by Dr. Erika Covi as part of the Groningen Cognitive Systems and Materials Center (CogniGron) and the Faculty of Science and Engineering at the University of Groningen.

Research topic

The group's main research focuses on the design of advanced cognitive systems. We work on bridging emerging memory systems and traditional semiconductor circuits to build new neuromorphic-memory systems. In this context, we can distinguish three different lines of research ranging from devices and circuits to learning systems that take into account the underlying hardware.

  1. Modelling and characterisation of emerging memory devices (ReRAM, FeCap).

  2. Design of neuromorphic circuits and systems.

  3. Hardware aware learning with emerging memory-based systems.
