SK Hynix Publishes CPO Roadmap in Prestigious Journal: Extending Optics Beyond Compute Interconnects to Memory Interfaces

SK Hynix, in collaboration with the University of Virginia and other institutions, published a CPO technology roadmap paper in Nature Electronics. The paper notes that while computing power grows 3x every two years, interconnect bandwidth only increases by 1.4x, making the "bandwidth wall" a core bottleneck for AI scaling. CPO technology is identified as a key breakthrough, with a longer-term vision of extending CPO to memory interfaces, enabling multiple AI accelerators to share a unified memory pool and improving memory utilization efficiency.
