Amidst the ongoing AI boom, China’s memory ambitions lurk around the corner

The industry’s biggest storage event, FMS 2026 confirmed that memory is no longer a supporting act in the AI story. It has become the bottleneck the entire industry is organizing around.

This analysis is authored by John Lorenz, Memory & Computing Director at Yole Group. It draws on a continuous strategic watch conducted throughout the year by Yole Group’s memory team, combining ongoing market monitoring with the team’s deep technical and business expertise. FMS 2026 serves as a checkpoint in that year-round work, a significant moment to confront Yole Group’s analysis against the latest signals from the industry’s leading players. It is this sustained, expert-driven approach that allows Yole Group to help its community stay ahead of market evolution, spot business breakthroughs early, and identify concrete opportunities as they emerge.

At FMS 2026, Samsung arrived with the show’s most aggressive technology concepts, all centered on wafer bonding: zHBM (HBM stacked directly on accelerator logic), zNAND-O for on-device AI, and a 400+ layer V-NAND generation built on the same bonding approach. Samsung’s LPDDR5X with processing-in-memory took home the show’s top award, signaling that compute-in-memory architectures are edging toward commercial reality.

SK hynix and SanDisk, meanwhile, jointly introduced High Bandwidth Flash (HBF) as a new Open Compute Project specification, vertically stacked NAND designed to deliver hundreds of gigabytes and multiple terabytes-per-second of bandwidth for inference and KV-cache workloads. In parallel, Kioxia pushed on commercialization, bringing PCIe 6.0 SSDs and extreme-capacity drives built for retrieval-heavy applications like RAG databases. To end, Micron, notably, focused less on new silicon and more on the economics of the current supercycle, reiterating that both DRAM and NAND remain in structural undersupply.

That undersupply is reshaping commercial relationships. Long-Term Agreements are evolving well beyond simple volume discounts: suppliers are locking in multi-year contracts with take-or-pay terms, price floors, and substantial customer deposits, trading pricing power for guaranteed revenue visibility. What was once a buyer’s market has clearly tilted toward suppliers, and this shift appears to be industry-wide rather than confined to the market leaders.

Even without a dedicated keynote, China’s two memory champions dominated hallway conversations throughout FMS 2026.

CXMT is shifting from a single-cluster build-out in Hefei toward a nationwide multi-fab strategy, adding capacity in Shanghai and Beijing. Wafer capacity stands at roughly 300K wafers per month today, with plans to more than double that at the next stage. However, a two-generation technology gap combined with lower yields translates into a meaningful bit-output penalty versus the established leaders. In this context, CXMT’s wafer volumes will outpace its effective bit capacity for some time. On the qualitative side, CXMT’s DDR5 has shown promising overclocking results and has been qualified with several major PC brands, even as voltage scaling and consistency continue to lag the industry’s top performers.

YMTC is pursuing a similar scale-first strategy in NAND, adding new fabs near its Wuhan base and targeting a technology roadmap that reaches 400-layer NAND by the end of the decade. Its approach prioritizes market share and domestic penetration, particularly in smartphones, over near-term profitability, aided by continued foundry partnerships and capital raised through IPO and joint-venture structures. Global NAND share attributed to YMTC has climbed to roughly 13%, up from under 12% the prior year, as detailed in Yole Group’s NAND Market Monitor.

The implication for the broader industry is significant: as Chinese capacity scales, it is expected to increasingly dominate commodity, legacy, and China-local demand, creating oversupply pressure in those segments while giving global leaders further incentive to concentrate on HBM and other high-value memory products. In other words, today’s Chinese capacity build-out could well become tomorrow’s pricing headwind in the lower end of the market, even as the high end remains structurally tight.

Underpinning all of this is a critical distinction, Yole Group’s analysts flagged repeatedly during discussions with customers at the show.

Today’s AI infrastructure spending is backed by demonstrable, fast-growing revenue, not speculative bets. Hyperscaler backlogs and inference-driven revenue growth suggest capex is being deployed with real payback expectations, which supports the case for a tight memory market persisting well into the medium term, even as China reshapes the commodity end of the business.
