What Happened to The Memory Price Fixing Scandal Involving Samsung, SK Hynix, and Micron?

The history of memory price fixing involving industry giants Samsung, SK Hynix, and Micron dates back to the early 2000s, marking a significant period of antitrust enforcement in the semiconductor industry. From 1999 to 2002, these companies, along with others like Infineon and Elpida, engaged in a conspiracy to fix prices for Dynamic Random Access Memory (DRAM). This cartel led to substantial fines and even prison sentences for several executives. Samsung pleaded guilty in 2005 and paid a $300 million fine, while SK Hynix (then Hynix Semiconductor) paid $185 million. Micron Technology avoided prosecution and fines by cooperating with the U.S. Department of Justice as a whistleblower.

Following this initial scandal, allegations of price fixing resurfaced. From 2016 to 2018, the Chinese government launched its own investigation into alleged anti-competitive practices by the 'Big Three' memory makers amidst a sharp rise in RAM prices. While no major fines were publicly announced by China in the same vein as the U.S. DOJ, the investigation highlighted ongoing concerns about market manipulation in the highly concentrated memory sector. A class-action lawsuit was also filed in the U U.S. in 2018 making similar claims about parallel production cuts, but it was dismissed in 2020, with the court ruling the conduct was 'more likely explained by lawful, unchoreographed free-market behavior.'

The current status, as of June 30, 2026, sees Samsung, SK Hynix, and Micron embroiled in a new, significant class-action lawsuit. Filed on June 25, 2026, in the U.S. District Court for the Northern District of California, the lawsuit alleges a 'coordinated scheme' to restrict DRAM supply and inflate prices, which have reportedly surged by approximately 700% over the past four years. The plaintiffs, a group of consumers and small PC businesses, claim that since 2022, the companies have deliberately cut production of conventional DDR3 and DDR4 memory while simultaneously shifting resources towards High-Bandwidth Memory (HBM), primarily used for AI data centers.

The lawsuit argues that this shift to HBM, while a legitimate business decision, was allegedly used as a pretext to create an artificial scarcity in the broader consumer DRAM market. Given that Samsung, SK Hynix, and Micron collectively control over 90% of the global DRAM market, the plaintiffs contend that this coordinated action makes no economic sense without collusion, as no new entrant can realistically challenge their dominance due to the immense capital and time required to build new fabrication facilities. The suit seeks class-action status, an injunction to halt the alleged supply restrictions, and treble damages. The defendants have not yet publicly responded to the new allegations, and the case is expected to be a protracted legal battle.

Regardless of the lawsuit's outcome, market analysts, such as Jefferies, predict that memory prices will continue to rise significantly through 2027, with no substantial relief expected before 2028. This sustained price increase is attributed to the overwhelming demand for HBM from the booming AI industry, which continues to cannibalize conventional DRAM production capacity. The ongoing legal challenges underscore persistent concerns about market concentration and potential anti-competitive behavior in the critical memory chip sector.
