A technology reseller in Sacramento who buys server memory by the pallet watched his cost per gigabyte climb for six straight weeks this spring. Distributors returned the same answer to every order: allocation. On June 25, that frustration reached federal court in California, where lawyers filed a class action accusing Samsung Electronics, SK Hynix and Micron Technology of holding back conventional DRAM supply while prices surged.
The lawsuit, filed on behalf of U.S. consumers and small businesses, says the three companies together control nearly all global production of DRAM, the dynamic random-access memory inside every computer, phone and server. During a period of sharply rising prices, the complaint alleges, the suppliers restricted output of traditional DRAM lines and deepened a shortage that has spread across the electronics industry. Analysts put Samsung’s share of the DRAM market near 40 percent, SK Hynix’s at roughly 30 percent and Micron’s at about a quarter, a concentration the plaintiffs say makes independent pricing almost impossible.
The timing lends the case weight. Days before the filing, Apple raised prices on several products, blaming higher memory costs, and handset makers in Asia followed with increases of their own. The complaint treats that sequence as evidence of coordinated scarcity, arguing that when three dominant suppliers tighten allocation at the same moment, prices move in step. Lawyers for the plaintiffs said they expect the class to cover millions of purchases of memory modules, personal computers and phones made over the past year.
The suit brings claims under federal antitrust law and state consumer-protection statutes, seeking damages, injunctive relief and restitution. It also names executives at the three companies as defendants, a structure plaintiffs’ lawyers use when they intend to push hard in discovery. The law firms leading the case have run similar actions against memory and display makers before, and their notices to potential class members describe the suit as a straightforward question of whether the world’s three DRAM suppliers agreed on scarcity.
The memory industry has been here before. In the mid-2000s, U.S. and European authorities fined Samsung, Hynix and Infineon Technologies over a DRAM price-fixing conspiracy, extracting hundreds of millions of dollars in penalties and sending several executives to prison in the United States. Those cases remain the benchmark for how a coordinated memory shortage looks once emails and meeting notes surface. The new complaint cites that history directly, arguing that the industry’s structure, three firms, heavy entry barriers and a largely interchangeable product, again creates the conditions for coordination.
None of the three companies responded to requests for comment. In prior cases, memory makers have denied colluding and attributed price moves to market forces.
Antitrust lawyers who have watched the case file say proving coordination will be difficult. Parallel price behavior alone is not illegal, and discovery will hinge on capacity decisions, allocation letters and any communications among the companies. The industry can also point to a genuine supply squeeze: high-bandwidth memory for AI accelerators consumes cleanroom capacity, and suppliers have shifted production lines away from commodity DRAM to chase richer margins. A person close to one of the suppliers said the company’s allocation letters to customers predate any discussion of litigation and reflect engineering reality, not strategy.
That squeeze is the backdrop to everything else. Memory prices have roughly tripled since the largest cloud companies announced sharp increases in capital spending, and the shortage has become a political issue. Lawmakers in Washington have held hearings on memory supply, and governments in Asia have weighed subsidies to expand production. The case also lands as South Korea’s largest chip makers commit more than $550 billion to new fabs and packaging capacity, a national response to a shortage that the lawsuit frames as partly manufactured. The legal front now runs alongside the subsidy front.
The costs are landing on ordinary buyers. PC makers have raised prices, server vendors have stretched lead times, and small businesses that run their own equipment face the steepest increases because they lack long-term contracts. The Sacramento reseller now quotes customers at prices he says would have seemed absurd a year ago. His order for the current quarter, placed in April, arrived with a surcharge notice attached.
Legal observers expect the fight over class certification to dominate the next year. Many price-fixing cases against memory suppliers have ended in settlements, with payouts running into the hundreds of millions of dollars, though the companies have also won dismissals when plaintiffs could not show agreement. If the class is certified, damages would be calculated from the gap between the prices plaintiffs paid and the prices they say a competitive market would have produced, a number that could grow with every quarter the shortage persists.
For now, the suit is one more pressure point on an industry navigating record demand and record scrutiny. A judge will decide whether the claims proceed. The reseller’s next pallet of modules, he said, will still cost more than the last.
