The UCIe specification includes covering:
Three primary protocol modes:
A chiplet designed for UCIe-2.5D can physically mate with any other UCIe-2.5D chiplet from any vendor, provided same bump map version. ucie spec
: The latest frontier (added in 2024), allowing chiplets to be stacked vertically for maximum density. The Result: The Chiplet Economy With a shared specification, a "chiplet economy" emerged. A designer could now take a high-performance compute core from one vendor, a specialized AI accelerator from another, and a memory controller from a third, and plug them together seamlessly. 12 sites Electronic Design - March/April 2024 UCIe presents one way to solve these problems. It fills the gap for industry- standard D2D interconnect that allows for the mixing... Electronic Design Industry Consortium Forms to Drive UCIe Chiplet Interconnect ...

Full protocol stack reuse (PCIe/CXL), ecosystem, and multi-vendor bump map. Electronic Design Industry Consortium Forms to Drive UCIe
The story of is a tale of the semiconductor industry’s shift from massive, "monolithic" chips to a modular world of chiplets . The Problem: The "Reticle Limit"
