Ucie Spec [hot] <2026>

As Moore’s Law slows, chiplet-based disaggregated System-on-Chips (SoCs) offer the path to higher performance, yield, and reusability. UCIe provides the "glue" to mix compute, memory, I/O, and analog chiplets from multiple sources.

UCIe 2.0 (released August 2024, backward compatible with 1.0/1.1). This guide covers both. ucie spec
