Semidynamics Unveils 3nm AI Inference Silicon and Full-Stack Systems

Semidynamics has taken a significant step forward in the race to build next-generation AI infrastructure with the unveiling of its 3nm AI inference silicon and a vertically integrated, full-stack systems strategy. Announced in February 2026, the development marks the company’s evolution from an advanced architecture specialist into a full-stack AI platform provider, delivering not only chips but also boards and rack-scale systems designed for demanding data center inference workloads. At a time when AI performance is increasingly constrained by memory efficiency and system integration rather than raw compute alone, Semidynamics’ approach reflects a clear shift toward system-level optimization.

Central to this announcement is the company’s successful 3nm tape-out with TSMC, achieved in December 2025. Fabricated using one of TSMC’s most advanced process technologies, this milestone validates Semidynamics’ ability to execute at the leading edge of semiconductor manufacturing. Tape-out at 3nm is not only a technical achievement but also a signal of silicon readiness, placing Semidynamics among a small group of companies capable of translating complex AI architectures into manufacturable, production-grade designs on the world’s most advanced nodes.

While the use of TSMC’s 3nm technology provides density, performance, and power-efficiency advantages, Semidynamics emphasizes that process scaling alone is not sufficient to meet the needs of modern AI inference. As AI models continue to grow in size and concurrency requirements increase, memory bandwidth and data movement have emerged as the dominant performance bottlenecks. This so-called “memory wall” limits the real-world gains achievable by compute-centric designs and drives up system cost and power consumption.

To address this challenge, Semidynamics has developed a new memory subsystem that rethinks data flow and memory access from first principles. Rather than relying heavily on scarce and expensive high-end memory components, the architecture optimizes how data is moved, reused, and accessed across the system. This enables large inference models to operate more efficiently, supports high-concurrency workloads, and reduces total cost of ownership for data center operators. The result is an architecture designed not just for peak performance, but for sustained, scalable inference in real deployment environments.

Building on this silicon foundation, Semidynamics is expanding into a full-stack AI infrastructure model. The company plans to deliver tightly integrated boards and rack-level systems based on its 3nm inference silicon, ensuring that architectural benefits at the chip level translate directly into system-level gains. This vertical integration is increasingly important in modern AI data centers, where performance, power efficiency, and scalability depend on how well accelerators, interconnects, and system software are co-designed.

By offering a complete stack (chips, boards, and racks), Semidynamics aims to reduce integration complexity for customers and provide predictable performance across multi-accelerator configurations. This approach contrasts with more fragmented models, where silicon vendors leave system optimization largely to OEMs and hyperscalers. For inference-heavy workloads that demand high throughput, low latency, and energy efficiency, such end-to-end optimization can be a decisive advantage.

Company leadership has positioned the 3nm tape-out with TSMC as a critical validation point in a broader, multi-stage roadmap. The goal is not simply to demonstrate advanced silicon, but to deliver production-ready AI inference platforms capable of operating at scale in next-generation data centers. This long-term perspective reflects Semidynamics’ architectural heritage and its focus on building durable platforms rather than one-off accelerators.

The announcement also carries strategic significance beyond technology. As a European-headquartered company designing advanced AI silicon manufactured at TSMC, Semidynamics represents a bridge between global manufacturing leadership and regional architectural innovation. This positioning aligns with broader efforts to strengthen Europe’s role in advanced computing while leveraging best-in-class foundry capabilities.

Bottom line: Unveiling its 3nm AI inference silicon and full-stack systems strategy, Semidynamics is addressing the realities of the current AI landscape. Performance gains are increasingly determined by memory efficiency and system integration, not just transistor counts. By combining an advanced 3nm implementation at TSMC with a memory-centric architecture and vertically integrated systems, Semidynamics is positioning itself as a differentiated player in AI inference infrastructure—one focused on scalable, efficient, and deployable solutions for the data centers of the future.
