The Chinese interface IP industry is entering an unprecedented window of opportunity.
By 2026, the global semiconductor industry is undergoing a structural transformation driven by AI. At the core of this shift, memory chips have moved beyond the conventional 3-4 year cycles dominated by consumer electronics and entered a supercycle fueled by large model training and inference.
Soaring HBM prices, order backlogs extending to 2027, and insufficient supply despite expansions by the three major manufacturers... Whether it's the AI computing power race or the memory capacity boom, the market has taken significant notice. However, in this wave of excitement, there is an almost overlooked "hidden winner": high-speed interface IP at the very top of the supply chain, which can be simply understood as "data transport capacity."
It does not manufacture memory chips or design AI computing cards, yet it is the indispensable "data highway" for every chip.
A Critical Link in the Supercycle The memory market in 2026 is setting records for price increases not seen in nearly a decade. According to TrendForce data, first-quarter DRAM contract prices surged 90%–95% quarter-over-quarter, with a projected further increase of 58%–63% in the second quarter. HBM, in particular, is in extremely short supply—premium HBM3E prices have risen over 80% compared to mid-2025. IDC data indicates that the global memory chip market size will skyrocket to $594.7 billion in 2026, a year-on-year increase of 163%, with the HBM market surpassing $30 billion, up 120% year-on-year.
Beyond memory chips, there is another easily overlooked segment in the semiconductor supply chain: the very upstream segment—semiconductor IP.
IP, or Intellectual Property, refers to mature designs of independently functional circuit modules within chips. Standardized and reusable, these allow chip design companies to quickly assemble complex chips, much like building with Lego blocks. Interface IP is a key category within this, encompassing memory interfaces and standard high-speed interfaces. Interface IP manages data exchange between chips and external devices, as well as between functional modules within a chip. A complete interface IP consists of a physical layer and a protocol controller, which together determine the bandwidth, latency, and energy efficiency of data transmission.
In the era of AI computing power, the strategic value of interface IP has been dramatically amplified. No matter how powerful the computing capability or how fast the memory, if data cannot flow in and out efficiently, the entire system's performance gets "stuck" on the road. This is what the industry commonly refers to as the "communication wall"—alongside the "performance wall" and "memory wall," it forms the triple physical constraints limiting chip development.
The Scale and Barriers of Interface IP The global interface IP market is on a rapid growth trajectory.
According to industry reports, the global interface IP market size grew from $1.065 billion in 2020 to $2.365 billion in 2024, with a compound annual growth rate (CAGR) of 22.08%. It is projected to reach $7.763 billion by 2030. The growth in the Chinese market is even more vigorous, reaching RMB 5.216 billion in 2024 and expected to hit RMB 19.953 billion by 2030, with a CAGR of 25.06%.
More noteworthy is the structural shift. The share of interface IP within the overall semiconductor IP market continues to climb, expected to rise from 27.85% in 2024 to 40% by 2030, surpassing processor IP to become the largest IP sub-category.
This trend clearly indicates that in the AI era, the efficiency of data interaction is becoming a more scarce competitive advantage than pure computing power.
From the perspective of downstream applications, demand for interface IP in AI-related fields is a primary driver. The Chinese AI-related interface IP market was RMB 1.708 billion in 2024 and is projected to reach RMB 9.178 billion by 2030, with a CAGR of 32.34%. The automotive electronics interface IP market is also growing at a remarkable pace, with an expected CAGR as high as 30.91%.
The core business model for interface IP vendors involves an upfront one-time licensing fee and backend royalties based on each chip's sales revenue. This means the revenue of IP vendors is closely tied to the sales volume and price of downstream chips—the combination of surging HBM unit prices and a sharp increase in shipments naturally boosts royalty income for interface IP. This represents a "light-asset, high-margin, long-term compound interest" business.
However, this high-growth, high-barrier, high-profit market has long been firmly dominated by overseas giants. According to reports, in 2024, Synopsys ranked first in the global interface IP market with a 59.70% share, followed by Cadence at 12.66%. Together, they control over 72% of the market. The overall market share of domestic Chinese vendors is only about 18%, and in advanced process nodes of 14nm and below, high-end interface IP is almost 100% reliant on imports.
The technological barriers are even more daunting. Interface IP is deeply intertwined with semiconductor manufacturing processes. At advanced nodes of 7nm and below, developing an interface IP can take 20–24 months. Once early entrants complete technical verification and ecosystem integration, it becomes nearly impossible for newcomers to catch up in the short term.
Accelerated Technology and Protocol Competition The iteration of interface protocol standards is accelerating across the board, which presents an opportunity for domestic vendors.
The evolution of the HBM protocol serves as the best example. The transition from HBM2 to HBM2E took about 4 years, while the shift from HBM2E to HBM3 was shortened to just 2 years. The HBM4 protocol was released in April 2025, adopting a 2048-bit interface with data transfer rates reaching 8Gbps and above, and total bandwidth increasing to 2TB/s. Each protocol upgrade necessitates re-verification and adaptation of interface IP, offering all participants a chance to reposition themselves.
The iteration of the PCIe protocol is also speeding up. The transition from PCIe 3.0 to 4.0 took 7 years, while 4.0 to 5.0 was shortened to 2 years. PCIe 6.0 was released in 2022, and 7.0 in 2025. For DDR, the shift from DDR3 to DDR4 spanned 6 years, DDR4 to DDR5 about 4 years, and DDR6 is expected to launch in 2026.
The introduction of each new generation standard resets the competitive landscape to some extent. Under new standards, all vendors start from a similar baseline—this is precisely the window of opportunity for latecomers to catch up or even surpass.
Fortunately, despite the long and challenging road, domestic IP vendors are striving to rise. Shanghai-based Xinyahui Technology is the leading domestic high-speed interface IP company and the only Chinese firm to have entered the global high-speed interface IP market. Its interface IP product line covers the most advanced protocol standards, including PCIe, DDR, HBM, D2D, SerDes, and HDMI, offering a full-stack, complete interface IP solution from the physical layer to the protocol controller. It has already achieved domestic interface IP coverage for advanced process platforms. This means a domestic vendor can provide "one-stop" interface IP services to chip design companies, rather than achieving breakthroughs only in individual products.
From Point Breakthroughs to Systematic Operations Founded in 2020, Xinyahui focuses on high-speed interface IP R&D. Its strategy involves entering the market with full product line coverage rather than solely betting on HBM. Simultaneously, its technical capabilities aim to match the international top tier. For instance, in the cutting-edge field of UCIe, its products have kept pace with the latest UCIe 2.0/1.1 standards, maintaining synchronization with overseas giants and achieving an absolute leading position domestically. In interface areas like DDR/LPDDR and HBM, it also operates at a level comparable to international vendors.
The value of this full-stack approach lies in two aspects: first, there are technological synergies between different interface IPs, where underlying technologies like signal integrity and power integrity in PHY design can be reused across products; second, chip design companies tend to procure multiple interface IPs from the same supplier to reduce integration risks, meaning that a more comprehensive product line strengthens customer loyalty.
It is reported that Xinyahui's products have served over 100 leading clients across various sectors, entering the supply chains of companies like ChangXin Memory Technologies, Cambricon, and Hygon.
According to industry reports, the localization rate of domestic interface IP in China has increased from nearly zero to about 18%. However, in certain specific sub-segments like HBM3E, overseas giants still dominate with a 92% share, while domestic self-sufficiency remains below 5%, creating a vulnerability to supply chain disruptions.
Therefore, to accelerate the industrialization of domestic interface IP, vendors like Xinyahui are actively building ecosystem collaboration with upstream and downstream partners in the supply chain. As China's leading DRAM manufacturer, ChangXin Memory is pushing hard for HBM localization—HBM2 samples were sent to customers in early 2026, with plans for HBM3 mass production by year-end. This "fast track" between IP design and memory manufacturing helps bypass over-reliance on overseas foundries, speeding up the verification and implementation of domestic interface IP, especially for memory interfaces.
The Window is Open, But Not Forever Despite significant challenges, the Chinese interface IP industry is entering an unprecedented window of opportunity.
On the demand side, domestic AI chip design companies are experiencing a surge in demand for high-speed interface IP. Regarding supply chain security, the U.S. has included semiconductor IP in its export control scope, making the construction of an autonomous and controllable supply chain system a "necessity" rather than an "option." On the policy front, the government is providing support through various dimensions, including finance, taxation, investment, financing, and R&D.
Reports predict that the global interface IP market will reach $7.763 billion by 2030, with the Chinese market hitting RMB 19.953 billion. Even if domestic vendors capture only 30%–40% of this market, it represents a multi-billion-yuan opportunity. Considering the current localization rate of less than 20%, the potential for future growth is substantial.
However, this window will not remain open indefinitely. Domestic IP companies do not have unlimited time. How to grow and strengthen rapidly in a short period is a challenge—and an opportunity—facing these tech firms. After all, each iteration of a new protocol standard requires IP vendors to make significant R&D investments in a short timeframe to compete for top clients. For international giants, this is a "familiar battlefield"; for domestic vendors, each protocol upgrade is like an "ice-breaking journey"—not only must they overcome the design challenges of the new standard itself, but they must also simultaneously address adaptation issues during process migration.
In the AI era, China's semiconductor industry is undergoing a paradigm shift from "efficiency first" to "balancing security and efficiency." Behind the competition for interface IP lies the biggest bet in China's tech industry. Only those players capable of advancing both technological catch-up and ecosystem building have the potential to transform from "light chasers" to "light emitters" in this supercycle.
