Samsung, Micron and SK Hynix Face Lawsuit Over Alleged DRAM Price-Fixing Scheme

Three of the world’s largest memory chip manufacturers—Samsung Electronics, SK Hynix, and Micron Technology—are facing a federal lawsuit in the United States over allegations that they conspired to restrict the supply of commodity DRAM memory chips, leading to a dramatic increase in prices over the past four years.

The lawsuit, filed on June 25 in the U.S. District Court for the Northern District of California, accuses the companies of coordinating production cuts to artificially limit the availability of widely used memory chips such as DDR3 and DDR4. According to the complaint, the alleged actions caused commodity DRAM prices to surge by approximately 700%, significantly increasing costs for consumers and businesses that rely on memory-based products.

The legal action was brought by 17 plaintiffs, including individual consumers and small businesses, who claim they suffered financial losses as a result of the alleged anti-competitive practices. The case has been assigned to Judge Noel Wise.

At the center of the complaint is the claim that Samsung, SK Hynix, and Micron used the industry’s shift toward High-Bandwidth Memory (HBM)—a technology increasingly in demand for artificial intelligence applications—as justification for reducing production of older DRAM products. The plaintiffs argue that while investment in HBM expanded, the companies deliberately tightened the supply of traditional memory chips, driving prices sharply higher.

The lawsuit seeks court intervention to end what the plaintiffs describe as an industry-wide effort to suppress supply. In addition to requesting an injunction, the plaintiffs are pursuing treble damages, which could significantly increase the financial liability if the allegations are proven in court.

The proposed class action also aims to represent a wider group of consumers and businesses that purchased products containing commodity DRAM during the period of rising prices.

As part of its argument, the complaint points to the broader impact of rising memory costs across the technology sector. It cites recent price increases for products such as Apple’s iPads and Mac computers as an example of how higher DRAM prices may have affected manufacturers and, ultimately, consumers.

The filing also references the companies’ previous legal history involving memory chip pricing. During the 2000s, both Samsung and SK Hynix pleaded guilty to separate U.S. Department of Justice charges related to DRAM price-fixing. Those cases resulted in a combined $731 million in criminal fines and prison sentences for several executives, a history the plaintiffs argue demonstrates a pattern of anti-competitive conduct within the industry.

The named plaintiffs include several individual consumers alongside small technology businesses, including Troy’s Computers LLC and JB Tech Solutions LLC, operating as My Florida PC.

At this stage, the allegations remain unproven, and the court has not determined whether Samsung, Micron, or SK Hynix violated U.S. antitrust laws. The lawsuit is expected to draw significant attention from the global technology industry, given the central role DRAM plays in smartphones, personal computers, servers, gaming devices, and artificial intelligence infrastructure.

If the case proceeds as a class action and the plaintiffs ultimately prevail, it could have far-reaching implications for the semiconductor industry, potentially reshaping competition and pricing practices in the global memory chip market.
