Definition
The physical and electrical connection between separate dies or chiplets in a package, including the signaling lanes and interface functions that allow data and control information to pass from one die to another.
Application
Used in multi-die and chiplet systems to provide short-reach, high-bandwidth, power-efficient communication; standardized interfaces such as UCIe define physical-layer and protocol requirements that support interoperability between chiplets.
