Semidynamics announced its expansion into full-stack AI infrastructure, unveiling a strategic roadmap to deliver high-performance inference silicon and vertically integrated systems. Building on its proprietary architecture, the company is developing chips, boards, and rack-level systems designed for the most demanding AI workloads in next-generation data centers.
Breaking the Memory Wall and 3nm Milestone
Semidynamics’ entry into the silicon market is built on years of architectural innovation. The company’s silicon architecture features a new memory subsystem designed to overcome bandwidth bottlenecks and mitigate supply constraints tied to high-end memory. By optimizing data flow and memory access, Semidynamics enables large-scale AI inference models to run more efficiently-supporting high-concurrency applications while reducing total cost of ownership.
In December 2025, Semidynamics achieved silicon readiness at the 3nm node-one of the most advanced process technologies in the world. This ‘tape-out’ milestone with TSMC marks a major step toward delivering production-grade chips and full-stack systems.
Semidynamics will offer a vertically integrated stack-chips, boards, and racks-targeting leading-edge, multi-accelerator AI platforms.

“Semidynamics has spent years mastering high-performance architecture at the fundamental level,” said Roger Espasa, CEO at Semidynamics. “We are now leveraging that expertise to solve the AI industry’s most critical challenges in memory and efficiency. Our successful 3nm tape-out is a vital technical validation as we execute a rigorous multi-stage roadmap toward delivering product-ready silicon and rack-scale systems. We are building a world-class, European-designed AI inference platform for the long term.”
Partner and Ecosystem Statements
Semidynamics’ approach is supported by partners across the AI and HPC ecosystem:
EuroHPC Joint Undertaking (EuroHPC JU) — Anders Jensen, Executive Director of the EuroHPC Joint Undertaking, commented, “I very much welcome the addition of a European-grown provider of advanced GPU chips to our AI ecosystem. This is a strategic milestone in strengthening Europe’s digital sovereignty and technological autonomy. Semidynamics has already been a key partner of the EuroHPC JU through the European Processor Initiative. We look forward to continuing our collaboration with innovative European suppliers like Semidynamics to power our supercomputers and AI Factories across Europe.”
The EuroHPC JU is the legal and funding entity that brings together the European Union and participating countries to coordinate efforts and pool resources to position Europe as a world leader in supercomputing. To this end, the EuroHPC JU has already procured 12 supercomputers across Europe including JUPITER and Alice Recoque, Europe’s first exascale systems. In parallel, the EuroHPC JU is overseeing the deployment of 19 AI factories across Europe, supported by 13 AI Factory Antennas.
