Samsung, SK hynix, and Micron sued over alleged DRAM price fixing amid record memory costs — lawsuit claims coordinated HBM shift was cover to curtail DDR3 and DDR4 production - Tom's Hardware

On June 25, 2026, a class-action lawsuit was filed in the U.S. District Court for the Northern District of California against Samsung Electronics, SK Hynix, and Micron Technology, accusing them of ill... Read original →

This lawsuit against Samsung, SK Hynix, and Micron reveals not just alleged price-fixing but the inherent fragility of a triopoly controlling over 95% of DRAM supply. Technically, while the industry’s pivot to HBM is AI-driven, synchronized cuts in DDR3/4 output artificially tightened legacy memory markets, spiking costs for PCs and IoT devices. Regulatory exposure is now acute: if the DOJ revives scrutiny—especially under heightened EU Chips Act transparency mandates—firms face mandatory capacity reporting and audit protocols. Competitively, second-tier players like Nanya (Taiwan, China) and CXMT (Mainland China) gain policy tailwinds despite limited scale, while AMD and Intel may fast-track CXL-based memory alternatives. Within 18 months, even without legal penalties, OEMs will enforce multi-sourcing clauses and demand decoupled HBM-DDR pricing, ending the era where 'technology transitions' mask coordinated supply restraint.
