Inside the history of DRAM price-fixing lawsuits — how HBM allocations could make a difference after two decades of failed cases - Tom's Hardware

This article delves into the two-decade history of DRAM price-fixing lawsuits, focusing on the latest case filed by Garciaguirre against Samsung, SK Hynix, and Micron. The suit alleges collusion durin... Read original →

The latest DRAM antitrust suit targeting Samsung, SK Hynix, and Micron—centered on HBM allocation—threatens to unravel tightly coupled technical and compliance dynamics. If courts compel disclosure of internal HBM supply decisions, it could expose systemic coordination in the AI memory stack, disrupting NVIDIA and AMD’s advanced packaging roadmaps. Even without a collusion verdict, defendants will face higher compliance costs from mandated transparency, likely accelerating test-and-assembly diversification to Taiwan, China and Southeast Asia. CXMT’s DDR5 ramp-up is already eroding the trio’s pricing hegemony. Over the next 12–24 months, this case may establish a new legal threshold for 'tacit supply restraint' under antitrust law, forcing memory buyers to demand ironclad supply guarantees—permanently altering the industry’s implicit trust framework.
