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

The 'Samsung, SK Hynix, Micron Memory Price Fixing Scandal' refers to ongoing allegations of anti-competitive behavior by the world's three largest memory chip manufacturers. The core of the current controversy is a class-action lawsuit filed on June 25, 2026, in the U.S. District Court for the Northern District of California. This lawsuit accuses Samsung Electronics, SK Hynix, and Micron Technology of engaging in a 'coordinated scheme' to restrict the supply of conventional Dynamic Random-Access Memory (DRAM), specifically DDR3 and DDR4 modules, since 2022.

Plaintiffs allege that the companies, which collectively control around 90% of the global DRAM market, used the industry's pivot towards High-Bandwidth Memory (HBM) for AI accelerators as a cover to deliberately curtail the production of older, commodity DRAM. This strategic shift, driven by HBM's significantly higher gross margins (three to five times that of conventional DRAM), allegedly created an artificial supply shortage, leading to a 'RAMpocalypse' where DRAM prices have surged by approximately 700% over a four-year period. The high barriers to entry in the memory chip manufacturing sector, with new fabs costing tens of billions of dollars and requiring years to build, further exacerbate the issue by preventing new competitors from entering the market and undercutting prices.

This is not the first time these companies have faced such accusations. In the early 2000s, Samsung and SK Hynix (then Hynix) pleaded guilty to criminal DRAM price-fixing charges brought by the U.S. Department of Justice. Samsung was fined $300 million in 2005, and SK Hynix paid $185 million, with several executives receiving prison sentences. Micron, however, avoided fines by cooperating with the investigation. A previous class-action lawsuit in 2018, making similar claims about parallel production cuts, was dismissed in 2020 and upheld on appeal in 2022, with the court ruling that the conduct was 'more likely explained by lawful, unchoreographed free-market behavior' rather than an illegal agreement.

The consequences of the alleged current price-fixing are widespread, impacting consumer electronics manufacturers and end-users alike. Companies like Apple have cited rising memory and storage costs for recent price increases on products such as Macs and iPads. Gaming console makers including Sony, Microsoft, and Nintendo have also raised prices or warned of higher hardware costs. In 2025, Micron notably announced its exit from the consumer DRAM market. The current lawsuit seeks class status, an injunction to halt the alleged coordinated supply restrictions, and treble damages.

As of June 30, 2026, the class-action lawsuit (Garciaguirre v. Samsung Electronics, case number 5:26 cv 06345) is in its early stages in the U.S. District Court for the Northern District of California, with an initial case management conference scheduled for September 29, 2026. The allegations remain unproven, and the defendants have yet to formally respond in court. Market analysts, such as Jefferies, predict that memory prices will continue to rise significantly through 2027, with no substantial relief expected before 2028, regardless of the lawsuit's outcome. The South Korean government has also indicated it will take action over soaring DRAM prices, including monitoring markets and pricing.
