Rana Walied Ahmad, M.Sc., successfully concluded his public doctoral defense on Wednesday, 28 January 2026, at RWTH Aachen University. The defense was held as a hybrid event.

The doctoral lecture, titled “Modeling and Simulation of Electrochemical Metallization Memory Cells for Neuromorphic Passive Crossbar Architecture,” addressed the modeling and simulation of electrochemical metallization memory cells, with a focus on their role in neuromorphic computing using passive crossbar architectures.

The successful completion of the defense marks the culmination of Rana Walied Ahmad’s doctoral research in the field of memristive devices and neuromorphic systems.

Emilio Perez-Bosch Quesada has completed his doctorate within the MIMEC framework in collaboration with IHP – Innovations for High Performance Microelectronics in Frankfurt (Oder). His doctoral research focused on HfO₂-based memristive devices, contributing to ongoing work on resistive memory technologies.

The research was carried out as part of the RRAM activities at IHP under the supervision of Eduardo Pérez Diez and Christian Wenger. During his doctoral studies, he worked closely with interdisciplinary teams and gained extensive experience in materials research and device characterization.

Following the successful completion of his doctorate, Emilio Perez-Bosch Quesada plans to continue his academic career in the field of memristors, further advancing research in this area.

The MemrisTec Summer School 2025 was successfully conducted in Sevilla, Spain, from 24 September to 3 October 2025, marking another milestone in the training and networking activities of the MemrisTec Research Unit. The event brought together early-career researchers, doctoral candidates, and leading scientists from partner institutions to explore the latest developments in memristive systems and neuromorphic electronics.

The comprehensive program combined keynote lectures, advanced tutorials, and hands-on laboratory sessions, covering topics ranging from molecular materials and device fabrication to computational modeling and circuit integration. Participants also had the opportunity to present their own research during poster sessions, fostering scientific dialogue and collaboration within the MemrisTec community.

Beyond the scientific sessions, the Summer School featured social and cultural activities in and around Sevilla, providing an excellent setting for networking and informal exchange among participants. The event once again demonstrated MemrisTec’s commitment to supporting interdisciplinary education and strengthening international collaboration in the field of memristive technologies.

Stefan Pechmann has successfully completed his PhD in Electrical Engineering at the Technical University of Munich (TUM). His doctoral defense took place a few weeks ago and concluded with the highest distinction, summa cum laude.

The dissertation, entitled “Integration of Multi-Level 1T1R RRAM Cells as Embedded Memory,” addresses key challenges in the integration of resistive random-access memory (RRAM) technologies for embedded applications. The work was carried out within the MIMEC environment at TUM and in close collaboration with the RRAM research group at IHP, contributing to ongoing efforts in advanced memory technologies.

The PhD project was supervised by Prof. Amelie Hagelauer and supported by an interdisciplinary examination committee. Over the course of his doctoral research, Stefan Pechmann worked on multi-level RRAM device concepts, combining system integration aspects with experimental and technological investigations.

Following the completion of his doctorate, Stefan Pechmann has transitioned to industry and has taken up a position as Hardware Developer at ZEISS Semiconductor Manufacturing Technology, joining via MCA Germany.

The MemrisTec community acknowledges this academic milestone and extends its best wishes for his continued professional career.

Sending electronics into space is no small feat. In Low-Earth Orbit, radiation, temperature extremes, and the vacuum pose challenges that conventional memory simply cannot withstand. The LEOMEM project, part of the DFG Priority Program MemrisTec and funded by the DFG starting in 2025, is addressing these issues. Researchers at TU Munich, University of Rostock, and IHP – Leibniz-Institute for Innovative Microelectronics, led by Prof. Amelie Hagelauer, Prof. Marc Reichenbach, and Prof. Christian Wenger, are developing radiation-resistant RRAM-based memory cells, building on results from the earlier MIMEC project.

First prototype chips, combining enclosed layout transistors (ELTs) with RRAM devices, have already been fabricated at IHP. These cells will undergo multi-stage testing for total ionizing dose (TID), single event effects (SEE), and extreme temperatures. Could memory survive these harsh conditions while remaining energy-efficient? That is one of the key questions LEOMEM seeks to answer.

At the system level, behavioral data from the devices will feed into a design framework to explore secure and adaptive memory architectures. Adaptive error correction codes will work alongside analog control, digital interfaces, and controllers in a fully integrated ASIC prototype. The ultimate goal is a memory system optimized for reliability, energy efficiency, and performance in space missions, paving the way for the next generation of in-memory computing beyond Earth.
