## Summary

Tamalika Banerjee and Ruben Hamming-Green, co-founders of IMChip, a spin-out from the University of Groningen, explain how their interface memristors offer greater reliability and scalability than filamentary devices by using lower voltages and preserving crystallinity during transfer. They detail a novel manufacturing process that grows these devices at high temperatures on lattice-matched substrates and then transfers them onto the back end of line (BEOL) of commercial CMOS chips, avoiding thermal budget constraints. The company aims to launch an edge-AI prototype chip within two years, targeting legacy nodes like XFab, while Giulia D’Angelo and Ralph Etienne-Cummings discuss the broader implications for neuromorphic computing and memcapacitors.
