The Chiplet Rebellion
Beyond Monoliths.
Manufacturing a single massive chip is expensive and yield-limited. **UCIe (Universal Chiplet Interconnect Express)** allows an AI architect to mix-and-match a 4nm TSMC compute chiplet with a 7nm I/O chiplet and an HBM3 memory stack, all on the same organic substrate.
UCIe provides the industry's first standardized **Die-to-Die (D2D)** interface. It offers PCIe-like reliability but with vastly higher throughput densities and a fraction of the power consumption, enabling multi-terabit communication between components as if they were on a single piece of silicon.
Package Scale
UCIe supports both Standard (organic) and Advanced (silicon interposer) packaging, allowing for 2.5D and 3D stacking of logic and memory.
Low Power PHY
Uses 1/20th the power per bit compared to traditional SerDes-based PCIe networking, allowing more energy for the Tensor cores.
