Innosilicon Scales LPDDR5X/5/4X/4 and DDR5/4 Combo IPs to 28nm and 22nm, Cementing Its Position as the ‘One Stop’ for Memory Interface Solutions

July 18, 2025 -- Pioneering the industry, Innosilicon has deployed two fully-compatible upgrade solutions LPDDR5/5X/4/4X Combo IP and DDR5/4 Combo IP across multiple global mainstream 28nm and 22nm process nodes, effectively helping customers tackle supply chain upgrade challenges.

With over 10 billion SoCs shipped and 19 years of high-speed IP innovation, Innosilicon is a trusted partner for delivering future-ready memory and interface IP across all major foundries and empowers global leading Tier-1 customers with successful mass-production.

As DRAM manufacturers phase out LPDDR4/4X and DDR4, many design teams face urgent upgrade pressures on legacy nodes. Innosilicon addresses this challenge directly with plug-and-play LPDDR5X/5/4X/4 and DDR5/4 IP covering global mainstream 28nm/22nm processes that enables seamless protocol switching, exceptional backward compatibility, and immediate readiness for volume production. These IPs have already been deployed in consumer, automotive, IoT, and embedded applications, ensuring supply continuity while minimizing redesign overhead.

Innosilicon’s LPDDR5X/5 and DDR5/4 Combo IPs have set world-record best performance benchmarks, validated by global leading customers in high-volume deployments. First introduced four years ago and validated at 10Gbps on 12nm, Innosilicon’s LPDDR5X/5/4X/4 Combo IP continues to set the standard for DRAM PHY and controller performance. The company has since delivered tailored GDDR6 IP at 28nm, 9.6Gbps HBM3E interfaces, PCIe 5.0/6.0 PHYs, UCIe chiplet integration, and 32G SerDes, highlighting its full-stack innovation engine.

Innosilicon’s memory interface portfolio combines high bandwidth, low power, and unmatched process portability. All solutions are backed by comprehensive RTL-to-GDSII delivery, mass-production testing support, and customization options, which help chip makers minimize risk while accelerating time to market.

Looking ahead, Innosilicon is extending its leadership with the upcoming LPDDR5X/6 Combo IP for 12nm–3nm, optimized for AI, HPC, and 8K-class multimedia. This dual-path strategy, supporting both mature-node continuity and advanced-node innovation, ensures chip makers have competitive, flexible IP choices for every stage of silicon evolution.

Innosilicon, a leading provider of one-stop IP and SoC services with 19 years of specialization in high-speed interface technologies.The company support global clients to achieve end-to-end product realization from design to volume production. Innosilicon’s industry-unique capability spans mainstream process nodes from 28nm to 3nm (28/22/14/12/8/7/6/5/4/3nm), enabling seamless cross-node migration while securing supply chain continuity. From securing current supply chains to powering the future of computing, Innosilicon delivers IP that is built to scale, built to perform, and built to last.
