The Post-Silicon Era Starts Here

The faster compute, more energy dilemma. AI needs efficiency—global data center power consumption will reach 945 TWh by 2030. Silicon alone cannot keep up beyond 2030.

FS2 develops "atomic" 2D semiconductors (2D Materials) that enable monolithic 3D integration at low temperature—compatible with legacy IC infrastructure.

AI Is Hitting a Wall.
We're Breaking Through It.

As AI models grow exponentially, the gap between compute speed and memory bandwidth widens every year. This is the Memory Wall — and it's becoming the defining bottleneck of the AI era.

The Bottleneck

AI models are scaling 240× every two years.
Memory bandwidth is not keeping up.

FS2's Answer

Stack memory directly on logic.
Eliminate the gap entirely.

FS2 is building the technology to break the Memory Wall — enabling the next generation of AI chips that are faster, denser, and radically more efficient.
