What Innosilicon does

Innosilicon is a privately held, China-headquartered fabless semiconductor IP and ASIC design company founded in 2006, specializing in high-speed mixed-signal interface IP and end-to-end custom silicon design services. The company employs over 1,300 people, including more than 1,000 R&D engineers, with global centers in Canada, the United States, China, the United Kingdom, and South Korea. Its core product portfolio spans three categories: memory interface IPs (GDDR7/6X/6 at up to 32 Gbps, LPDDR6/5X at 14.4 Gbps, HBM4/3E at 10 Gbps, DDR5/4 MRDIMM at 12.8 Gbps), interconnect IPs (PCIe 6.0/5.0, UCIe-compliant Innolink Chiplet, UALink at 112G/224G, and 112G/64G/32G multi-protocol SerDes), and multimedia interface IPs (HDMI, DP/eDP, MIPI, USB 3.2/2.0). Process node coverage extends from 65nm/55nm down to 3nm, with silicon-proven qualification across TSMC, Samsung, GlobalFoundries, SMIC, UMC, and Intel Foundry.

The company generates revenue through two primary streams: licensing of silicon-proven IP cores (PHY and controller combinations) with licensing fees and royalties, and full-stack custom ASIC design services spanning front-end design, physical back-end design, PPA optimization, advanced packaging (including 2.5D/3D), and turnkey manufacturing. Supporting offerings include multi-project wafer (MPW) services and chip testing/prototyping. Customer base includes over 300 worldwide semiconductor and systems companies, with named tier-one logos spanning AMD, Microsoft, Amazon, Qualcomm, Huawei, ZTE, Rockchip, Cypress, and Microchip. The company claims 10 billion+ SoCs shipped with embedded IP, over 300 successful tapeouts, and 150,000 FinFET wafers per year of custom ASIC production capacity.

Go-to-market is direct enterprise sales targeting semiconductor companies, supplemented by participation in industry events (TSMC OIP Ecosystem Forum, Samsung Foundry Forum, DesignCon, GLOBALFOUNDRIES events) and technical white paper publication. Vertical segmentation covers AI/HPC semiconductors (data center accelerators, GPU/NPU/HPC chips), automotive electronics (ISO 26262 compliant), 5G and wireless communications, IoT/edge AI, and consumer multimedia. Pricing is quote-based and not publicly disclosed. Strategic differentiation rests on industry-first product introductions (first commercial LPDDR6 in China, first UCIe-compliant chiplet, world's fastest GDDR7), one-stop IP and ASIC portfolio, multi-foundry coverage, and consortium participation in UALink alongside AMD, Google, Microsoft, and Alibaba.
