Technical Deep Dive: Unpacking Eliyan's NuLink Innovation
Eliyan's modular semiconductor technology, primarily its NuLink and NuLink-X PHY solutions, represents a significant leap forward in chiplet interconnects. At its core, NuLink PHY is a high-speed serial die-to-die (D2D) interconnect, while NuLink-X extends this capability to chip-to-chip (C2C) connections over longer distances on a Printed Circuit Board (PCB). The technology boasts impressive specifications, with the NuLink-2.0 PHY, demonstrated on a 3nm process, achieving an industry-leading 64Gbps/bump. An earlier 5nm implementation showed 40Gbps/bump. This translates to a remarkable bandwidth density of up to 4.55 Tbps/mm in standard organic packaging and an even higher 21 Tbps/mm in advanced packaging.
A key differentiator is Eliyan's patented Simultaneous Bidirectional (SBD) signaling technology. SBD allows data to be transmitted and received on the same wire concurrently, effectively doubling the bandwidth per interface. This, coupled with ultra-low power consumption (less than half a picojoule per bit and approximately 30% of the power of advanced packaging solutions), provides a significant advantage for power-hungry AI workloads. Furthermore, the technology is protocol-agnostic, supporting industry standards like Universal Chiplet Interconnect Express (UCIe) and Bunch of Wires (BoW), ensuring broad compatibility within the emerging chiplet ecosystem. Eliyan also offers NuGear chiplets, which act as adapters to convert HBM (High Bandwidth Memory) PHY interfaces to NuLink PHY, facilitating the integration of standard HBM parts with GPUs and ASICs over organic substrates.
Eliyan's approach fundamentally differs from traditional interconnects and silicon interposers by delivering silicon-interposer-class performance on cost-effective, robust organic substrates. This innovation bypasses the need for expensive and complex silicon interposers in many applications, broadening access to high-bandwidth die-to-die links beyond proprietary advanced packaging flows like Taiwan Semiconductor Manufacturing Company (NYSE: TSM) TSMC's CoWoS. This shift significantly reduces packaging, assembly, and testing costs by at least 2x, while also mitigating supply chain risks due to the wider availability of organic substrates. Initial reactions from the AI research community and industry experts have been overwhelmingly positive, with comments highlighting its ability to "double the bandwidth at less than half the power consumption" and its potential to "rewrite how chiplets come together," as noted by Raja Koduri, Founder and CEO of Mihira AI. Eliyan's strong industry backing, including strategic investments from major HBM suppliers like Samsung (KRX: 005930), SK Hynix (KRX: 000660), and Micron Technology (NASDAQ: MU), further underscores its transformative potential.
