Eliyan raises $60M for chiplet interconnects that pace up AI chips

Be a part of Gen AI enterprise leaders in Boston on March 27 for an unique evening of networking, insights, and conversations surrounding knowledge integrity. Request an invitation right here.

Eliyan has raised $60 million in funding for its chiplet interconnect expertise that accelerates the processing for AI chips.

Samsung Catalyst Fund and Tiger International Administration each led the spherical to assist the group deal with the challenges of improvement of generative AI chips. Pushed by demand for AI chips, {industry} forecasters are calling for strong development within the high-bandwidth reminiscence (HBM) sector, as a lot as 331% enhance this yr, adopted by 124% in 2025, based on market researcher Arete Analysis.

Eliyan’s UCIe-, BoW-, or UMI-compliant PHY (dubbed NuLink PHY) addresses reminiscence and IO wall constraints on both superior or customary packaging materials. A PHY is a bodily layer of the OSI mannequin. An instantiation of PHY connects a hyperlink layer machine (usually known as a MAC) to a bodily medium resembling an optical fiber or copper cable. Now it’s being utilized to multi-chip options, which permit chip makers to attach a number of chiplets on the identical machine.

Eliyan’s chiplet interconnect expertise achieves as much as 4 occasions the efficiency and half the facility of different options, the corporate stated.

The AI Influence Tour – Atlanta

Persevering with our tour, we’re headed to Atlanta for the AI Influence Tour cease on April tenth. This unique, invite-only occasion, in partnership with Microsoft, will characteristic discussions on how generative AI is remodeling the safety workforce. House is proscribed, so request an invitation right now.

NuLink PHY is confirmed on superior course of nodes, addresses each Die-to-Die and Die-to-Reminiscence interconnect with its extremely environment friendly efficiency metrics.

Present buyers additionally participated within the spherical, together with Intel Capital, in addition to SK Hynix, Cleveland Avenue and Mesh Ventures, amongst others.

The extra funding follows the corporate’s $40 million Sequence A spherical in 2022. It can allow Eliyan to proceed its deal with essentially the most urgent challenges dealing with the design and manufacturing of superior AI chips that use multi-die architectures in both superior packaging or customary natural substrates. Its chiplet interconnect expertise permits chip makers to realize new ranges of efficiency and energy effectivity.

Along with die-to-die interconnect in chiplet-based designs, the corporate addresses the rising problem of reminiscence capability and bandwidth in AI chips with its modern Common Reminiscence Interface (UMI). The bi-directional interconnect methodology goals on the “reminiscence wall” situation dealing with giant, multi-die designs.

“We’re thrilled to co-lead Eliyan’s Sequence B spherical and associate with an distinctive group identified for his or her distinctive experience in interconnect and blended sign applied sciences,” stated Marco Chisari, head of Samsung Semiconductor Innovation Heart, in an announcement. “Intensive workloads and cutting-edge purposes, together with Generative AI and automotive, are driving the demand for extra subtle semiconductor design and the adoption of chiplet structure.”

UMI permits a really bandwidth-efficient connection to reminiscence, in each customary natural substrates and superior packaging. Given its extremely environment friendly PHY beachfront space, UMI offers a major enhance in combination reminiscence bandwidth per AI chip and main die space discount wanted for reminiscence interfaces.

“At a time when the explosion of AI is driving rising connectivity wants and the semiconductor {industry} is present process a seismic shift with the rise of multi-die implementation, Eliyan is poised to revolutionize chiplet connectivity expertise by unleashing the last word efficiency of chiplet-based programs,” stated Srini Ananth, managing director at Intel Capital, in an announcement. “Eliyan’s continued developments in die-to-die interconnect structure and its scalability within the AI period, really marks a major milestone within the bigger chiplet revolution.”

Eliyan’s NuLink PHY lately taped out on TSMC’s 3nm course of, concentrating on industry-leading efficiency of as much as 64Gbs per hyperlink, at an unprecedented efficiency/energy ratio.

“This funding displays the boldness in our method to integrating multi-chip architectures that deal with the essential challenges of excessive prices, low yield, energy consumption, manufacturing complexity, and dimension limitations,” stated Ramin Farjadrad, CEO of Eliyan, in an announcement. “Our NuLink expertise has achieved industrial readiness with tape outs in essentially the most superior processes, and is optimized for delivering the mandatory excessive bandwidth, low latency, and low energy capabilities. We thank all of our buyers for his or her assist of our imaginative and prescient of enabling the last word chiplet programs for the brand new AI period.”
