Samsung, SK Hynix, and Micron are facing a US antitrust class action alleging they fixed DRAM prices and supply during an ongoing memory shortage. Multiple outlets report the case is filed in California, in the Northern District. The complaint is brought by multiple plaintiffs and alleges the three major memory chipmakers—described as producing nearly all global DRAM—coordinated actions that limited commodity DRAM availability and helped keep prices high.
According to the suit as summarized by the outlets, the companies allegedly reduced or restricted output of certain DRAM types such as DDR3 and DDR4, while shifting production focus toward higher-value memory used in AI data centers, including high bandwidth memory (HBM). Plaintiffs argue that these coordinated pivots constrained supply for consumer and other non-AI segments, worsening the RAM crisis. Several sources also characterize the companies as “oligopolists” and allege the behavior resulted in “supracompetitive” prices.
The articles describe the lawsuit as a class action and note it represents a recurring pattern of similar allegations against the same firms.
