A U.S. class-action lawsuit filed in California accuses Samsung Electronics, SK hynix, and Micron of colluding to restrict DRAM supply and raise prices during an ongoing memory and storage cost surge. Plaintiffs, numbering seventeen in some accounts, allege the companies engage in “concerted anticompetitive behavior” and form an “oligopoly” that prevents outside competitors from disciplining the market through new production. The complaint argues the firms coordinated shifts away from mainstream consumer DRAM output such as DDR3 and DDR4, and toward higher-value High-Bandwidth Memory (HBM) used primarily in AI data centers. Plaintiffs contend that these supply moves contributed to higher commodity memory pricing affecting PCs, gaming hardware, and other electronics.

Some reporting notes that the suit also references earlier alleged price-fixing cycles involving the same manufacturers, including past regulatory outcomes for DRAM pricing. Micron disputes the allegations and says it will defend itself, while the lawsuit is seeking damages and injunctive relief to stop the alleged collusion. Apple is not accused of wrongdoing, though the suit’s claims involve memory suppliers used across Apple products.
