New Lawsuit Challenges Samsung, SK hynix, Micron Over DRAM

A new lawsuit claims the world's biggest memory makers worked together to limit DRAM supply and keep prices high, but proving those allegations could be easier said than done.

Building or upgrading a PC has become noticeably more expensive over the past few years, and memory is one of the biggest reasons why. RAM prices have continued to climb when many buyers expected them to settle down. Now, that growing frustration has turned into legal action, with three of the world's largest memory manufacturers facing allegations that they helped drive those price increases.

A class action lawsuit has been filed in the U.S. District Court for the Northern District of California against Samsung Electronics, SK hynix, and Micron. The complaint, filed on June 25 under the name Garcia v. Samsung Electronics, accuses the companies of engaging in anti-competitive practices in the DRAM market starting around 2022.

The lawsuit argues that the companies intentionally reduced the supply of traditional DRAM while shifting more of their manufacturing toward high-bandwidth memory (HBM), the premium memory now in huge demand for AI servers and data centers. Since Samsung, SK hynix, and Micron control roughly 90% of the global DRAM market, the complaint claims their decisions had a major impact on prices across the industry.

Supplies of older memory types like DDR3 and DDR4 gradually became tighter as production slowed.

That left buyers with fewer affordable options and pushed more demand toward DDR5, which has remained significantly more expensive. For many gamers, PC builders, and hardware enthusiasts, the result has been the same—paying much more for a memory upgrade than they would have just a few years ago.

Reports cited in the lawsuit suggest DRAM prices have jumped dramatically over the last four years, with some estimates putting the increase at around 700%. Those rising costs have been felt across the IT industry, from gaming PCs and laptops to graphics cards and other consumer goods. So, what's really behind these higher prices? That's the question this case hopes to answer.

The lawsuit claims the companies increasingly focused on producing HBM because it delivers much higher profits thanks to the AI boom. As demand from major AI companies exploded, more manufacturing capacity was directed toward data-center memory, while traditional consumer DRAM became less of a priority.

The complaint also points to history. Samsung, SK hynix, and Micron were all linked to DRAM price-fixing investigations in the early 2000s, cases that resulted in legal action and financial penalties. Those past instances don’t establish today’s charges, but the lawsuit says they provide vital context to interpret current market activity.

It is not easy, however, to win an antitrust action such as this. Market forces tend to push companies in the same direction, and therefore they tend to make similar business decisions. That alone is insufficient to prove illegal cooperation. Plaintiffs will likely have to provide strong evidence of collusion between the companies, including internal emails or agreements that demonstrate a coordinated effort to restrict supplies.

Without that kind of proof, the lawsuit may have a tough time winning even as customers continue to ask why memory prices remain so high.

Plaintiffs are seeking monetary damages and court orders to prevent any future anti-competitive behavior if the claims are confirmed. But class action actions against major digital companies tend to drag on for years before a final outcome is reached. In the meanwhile, the case highlights a sector at the heart of modern computing.

The demand for AI continues to transform the semiconductor sector, leaving consumers wondering if the rising prices of RAM are simply the new norm or if something more is happening behind the scenes. The courtroom battle has only just begun, but could it finally reveal what's really been driving the cost of memory all this time?
