What Happened to Samsung, SK Hynix, Micron Sued in US over Memory Price Fixing?
In June 2026, Samsung, SK Hynix, and Micron Technology, the dominant players in the global DRAM market, were hit with a class-action lawsuit in the U.S. District Court for the Northern District of California. The lawsuit alleges that the companies colluded to artificially inflate DRAM prices by restricting the supply of conventional memory chips since 2022, under the guise of shifting production to high-bandwidth memory (HBM) for AI applications. This alleged coordinated behavior has led to a dramatic surge in memory prices, impacting consumers and businesses alike.
Quick Answer
Samsung, SK Hynix, and Micron Technology are currently facing a class-action lawsuit filed on June 25, 2026, in the U.S. District Court for the Northern District of California. The plaintiffs, a group of consumers and small businesses, accuse the three memory giants of engaging in a coordinated scheme since 2022 to restrict the supply of conventional DRAM and inflate prices by approximately 700%, using the increased demand for AI-specific HBM as a pretext. The lawsuit seeks class status, an injunction to stop the alleged anticompetitive practices, and treble damages.
📊Key Facts
📅Complete Timeline13 events
Initial DRAM Price-Fixing Conspiracy
Samsung and Hynix (now SK Hynix) engaged in a criminal conspiracy to fix DRAM prices.
Guilty Pleas and Fines in Previous Price-Fixing Case
Samsung pleaded guilty to the U.S. Department of Justice and was fined $300 million, while SK Hynix was fined $185 million for their roles in the DRAM price-fixing cartel. Micron avoided penalties by cooperating.
Another Period of Alleged Price Fixing
A separate class-action lawsuit was filed against Samsung, Micron, and SK Hynix alleging price fixing during this period.
Class Action Lawsuit Filed (2016-2017 Allegations)
Law firm Hagens Berman brought a class action lawsuit making similar claims about parallel production cuts.
Dismissal of 2018 Class Action
The U.S. District Court dismissed the 2018 class action lawsuit.
Ninth Circuit Upholds Dismissal; Alleged New Collusion Begins
The Ninth Circuit Court of Appeals upheld the dismissal of the 2018 lawsuit, ruling the conduct was 'more likely explained by lawful, unchoreographed free-market behavior.' Simultaneously, the new class action alleges that Samsung, SK Hynix, and Micron began their current alleged scheme of supply restriction and price fixing.
DRAM Prices Surge by ~700%
Over this four-year period, conventional DRAM prices allegedly surged by approximately 700% due to coordinated production cuts and a shift to HBM.
Shift to HBM Production Intensifies
The companies allegedly shifted significant resources from conventional DRAM to High Bandwidth Memory (HBM) to support AI demand, further reducing commodity DRAM availability.
Micron Reduces Earnings Guidance
Citing a drop in NAND demand, Micron issued reduced earnings guidance, which allegedly caused its stock price to drop.
Micron Shuts Down Crucial Consumer Brand
Micron shuttered its consumer sub-brand Crucial, which plaintiffs cite as an example of artificially cutting supply at a profitable point.
Micron Securities Class Action Dismissed
A putative securities class fraud action against Micron Technology and its executives was dismissed by the U.S. District Court for the District of Idaho, which found that the amended complaint did not adequately plead falsity or scienter.
New Class-Action Lawsuit Filed in US
A class-action lawsuit (Garciaguirre v. Samsung Electronics, Case No. 3:26-cv-06345) was filed in the U.S. District Court for the Northern District of California against Samsung, SK Hynix, and Micron, alleging DRAM price-fixing.
Current Status: Lawsuit in Early Stages
As of today, the lawsuit has just been filed. No official responses from the defendant companies have been issued, and no trial date has been set. Analysts predict memory prices will continue to rise through 2027-2028.
🔍Deep Dive Analysis
The latest legal challenge against Samsung, SK Hynix, and Micron Technology, filed on June 25, 2026, in the U.S. District Court for the Northern District of California, marks a significant development in the ongoing memory market volatility. The class-action lawsuit, titled 'Garciaguirre v. Samsung Electronics,' alleges that these three companies, which collectively control over 90% of the global DRAM market, have engaged in concerted anticompetitive behavior since 2022.
The core accusation is that the memory manufacturers deliberately restricted the supply of conventional DRAM (DDR3 and DDR4) by simultaneously cutting production and coordinating a pivot towards High Bandwidth Memory (HBM), primarily used in AI data centers. Plaintiffs argue that this shift was a pretext to create an artificial shortage in the consumer-grade DRAM market, driving prices up by an estimated 700% over four years. This alleged collusion, rather than pure market dynamics, is blamed for the 'RAMpocalypse' and the subsequent price increases across various consumer electronics, including PCs, MacBooks, and gaming consoles.
This isn't the first time these companies have faced such allegations. Samsung and SK Hynix (then Hynix Semiconductor) pleaded guilty to criminal DRAM price-fixing in the early 2000s, resulting in fines of $300 million and $185 million, respectively, with several executives serving prison sentences. Micron avoided penalties at that time by cooperating with the investigation. A previous class-action lawsuit filed in 2018, alleging price-fixing from 2016-2017, was dismissed in 2020 and upheld on appeal in 2022, with courts ruling the conduct was 'more likely explained by lawful, unchoreographed free-market behavior.' The current lawsuit, however, leans on the coordinated HBM pivot as new evidence of collusion.
Consequences of the alleged actions include significantly higher costs for consumers and businesses, with some reports indicating that memory prices could continue to rise by 40-50% in Q3 2026 and another 30-40% in Q4, with no meaningful relief expected before 2028. The lawsuit seeks class status to represent all affected consumers and businesses, an injunction to halt the alleged anticompetitive practices, and treble damages. As of June 30, 2026, the lawsuit has just been filed, and the defendant companies have not yet issued official public comments in response. The legal process is in its early stages, with no trial date set.
