XCENA Raises $135M, Bets on Memory-Centric AI Chips
XCENA, a four-year-old chip startup with offices in South Korea and the U.S., raised $135 million in a Series B at a $570 million valuation (bringing total funding to $185 million) to commercialize a memory-centric chip designed to move compute closer to DRAM. XCENA’s MX1 prototype uses CXL (Compute Express Link) to process data within memory modules and relies on many small RISC-V cores and a custom internal memory hierarchy. Founders Jin Kim (CEO), Dohun Kim (CTO) and Harry Juhyun Kim (CPO) are veterans of Samsung and SK Hynix. The company expects Samsung-foundry mass production by end of 2026 and revenue beginning in 2027, and counts Seoul VCs Altinum and IMM Investment among the Series B co-leads. XCENA targets hyperscalers and cites rivals including Astera Labs and Marvell.
A sizable Series B for a startup targeting AI inference infrastructure could materially affect AI operational costs if the memory-centric approach scales; the funding, Samsung foundry production timeline, and hyperscaler target customers make it notable for infrastructure and hardware supply chains.

SCI Semiconductor Raises £5M for Memory-Safe Chips
Sheffield-based SCI Semiconductor, developer of the world's first memory-safe computer chip, has raised £5 million to accelerate production. The oversubscribed round was co-led by PXN Ventures and Mercia Ventures, with participation from Osney Capital, Black Opal Ventures, and private investors. The funding will scale production of its ICENI chips, based on CHERI technology, addressing memory safety vulnerabilities behind ~70% of cyberattacks. SCI has secured orders worth £2 million and government contracts totaling £7.7 million, including as a core supplier in the UK's Accelerated CHERI Adoption Programme. Partnerships with Google Research and Microsoft and compliance with the EU Cyber Resilience Act position the company for growth. Founded in 2022, the company plans to create 15 new jobs.
China’s CXMT Poised to Challenge DRAM Incumbents
CXMT, founded in 2016, has rapidly scaled into China’s leading DRAM supplier and is preparing a high‑profile IPO on Shanghai’s STAR Market. The company’s technology and capability trace to licensed Qimonda DRAM patents and documentation plus recruited tacit know‑how from former Qimonda, US, Korean and Taiwanese engineers. Strong state and municipal backing (notably Hefei) supplied patient capital and a localized supply chain. CXMT’s FY2025 revenue surged (~156% YoY to ~$8.6B) and consolidated net income turned positive (RMB7.14B, with RMB1.87B attributable to parent). The firm is expanding wafer capacity (projected ~350 kwspm by end‑2026) and increasing bit market share (modeled ~9% in 2025 to ~12% in 2027). Analysts emphasize that recent margin and profit gains are driven mainly by a strong pricing cycle and ASP increases rather than dramatic cost parity or superior yields versus Samsung, SK Hynix and Micron. CXMT’s HBM capability remains limited and poses technical yield and stacking challenges.
Dutch AI chip startup EUCLYD raises €200M Series A
Dutch semiconductor startup EUCLYD, based in Eindhoven, has raised over €200 million in a Series A funding round to develop ultra-efficient infrastructure for foundation AI models. The round was co-led by Samsung, Somerset Capital Partners, the EQT-managed Scaleup Europe Fund, and Innovation Industries, with additional participation from EIFO, imec.xpand, Brabant Development Agency (BOM), and Quadri. Peter Wennink, former CEO of ASML, joins as Chairman. Founded in 2024 by Bernardo Kastrup and Atul Sinha, EUCLYD focuses on compute and memory bottlenecks in AI data centers, offering products like 'craftwerk' and 'craftwerk station CWS'. The funding will be used to expand engineering teams, accelerate product development, and target enterprise, government, and hyperscale markets.
