Key Takeaways
Created with AI - we're still experimenting, so apologies if it misses the mark
- A class-action lawsuit has been filed against Samsung, SK Hynix, and Micron in the U.S., alleging that they intentionally limited memory supply to artificially inflate prices, specifically DDR3 and DDR4 RAM.
- The complaint suggests that these companies favored High Bandwidth Memory (HBM) production over traditional DRAM, as it is more profitable due to increased demand from AI-focused data centers.
- The lawsuit claims this strategy led to a shortage of standard memory and dramatic price increases for consumers and manufacturers of various electronics, including PCs, consoles, and other electronics.
- This lawsuit follows a separate lawsuit against Micron by Powerchip Semiconductor and SK Hynix, alleging unfair competition in the global memory market, including price fixing, bid rigging, and other anticompetitive practices. These lawsuits could result in substantial damages if proven and may lead to compensation for consumers and businesses who paid inflated prices for their components.

Memory and storage component prices have been rising for months, driving up the cost of many technology products, including consoles, graphics cards, PCs, and Steam Machines. Manufacturers have cited increased component costs, largely attributed to the AI boom, as justification for these price increases. However, a new class-action lawsuit filed in the U.S. may challenge this narrative. Samsung, SK Hynix, and Micron are accused in a class-action lawsuit of intentionally limiting memory supply to artificially inflate prices. The complaint alleges that these companies deliberately restricted production of DDR3 and DDR4 RAM, favoring the more profitable HBM (High Bandwidth Memory) instead. This strategy allegedly squeezed the traditional memory market, causing prices to skyrocket for regular buyers. In a competitive market, high prices typically encourage increased supply. However, the lawsuit claims this did not happen because the three companies allegedly continued to tighten supply, sometimes abandoning conventional DRAM channels entirely.
According to the complaint, relayed by Law360, these three companies, which dominate the global DRAM market, coordinated their production strategies. They voluntarily reduced the volume of DDR3 and DDR4 memory intended for the general public, redirecting production capacity to HBM. This shift was driven by the explosive demand from data centers focused on AI, making HBM significantly more profitable. The plaintiffs believe this strategy artificially created a shortage of standard memory, leading to a dramatic price increase for both consumers and manufacturers of PCs, consoles, and other electronics. They argue that in a truly competitive market, a price surge would have prompted at least one manufacturer to increase production to gain market share.
Samsung, SK Hynix, and Micron face a new class-action lawsuit filed in the U.S. on June 26, 2026, under case number 3:26cv06345. This action follows a separate lawsuit where Powerchip Semiconductor from Taiwan and SK Hynix from South Korea took U.S. chipmaker Micron Technology to court. The Powerchip and SK Hynix lawsuit accuses Micron of unfair competition in the global memory market, alleging price fixing, bid rigging, and other anticompetitive tactics to keep DRAM and NAND flash memory chip prices high. Filed in the United States District Court for the Northern District of California, this case seeks damages and a court order to halt Micron’s alleged anticompetitive practices. Powerchip and SK Hynix contend that Micron’s actions have harmed consumers by artificially boosting memory chip prices across various products, including smartphones, computers, and servers.
This lawsuit emerges at a time of extraordinary demand in the global memory market, driven by data-heavy applications like AI, machine learning, and 5G networks. The suit alleges that Micron has exploited this high demand to engage in anticompetitive practices to protect its market share and profit margins. Powerchip and SK Hynix are seeking a jury trial, which could result in substantial damages if their accusations are proven. Micron has not yet responded to the lawsuit, but the company has faced similar antitrust allegations previously. In 2018, Micron paid $95 million to settle charges of price fixing and bid rigging related to DRAM and NAND flash memory chips. The lawsuits also highlight the significant barriers to entry in the DRAM manufacturing sector. Establishing a new DRAM fabrication facility requires tens of billions of dollars in investment and several years of development, in addition to proprietary production process knowledge. Furthermore, American export restrictions on certain technologies to China could further limit the emergence of new competitors.
Antitrust Lawsuit Accuses Micron, Powerchip, SK Hynix of Memory Price Manipulation Impacting Tech Industry
The three companies involved are no strangers to such accusations. In 2005, Samsung and SK Hynix pleaded guilty to DRAM price-fixing charges in a U.S. case, while Micron avoided punishment by cooperating with authorities. Additionally, Chinese authorities opened an investigation between 2016 and 2018 following another price surge. This legal action coincides with the ongoing impact of rising memory costs across the technology industry. Microsoft recently cited multiplied storage and memory costs, exceeding 2.5 times their previous levels, as a reason for price increases on the Xbox Series. Valve also raised the price of its Steam Machine, and Sony, Nintendo, and Apple have similarly increased prices on several products in recent months. If these lawsuits succeed, they could lead to compensation for consumers and businesses who paid inflated prices for their components. In the meantime, these actions shed light on the mechanisms that may explain the recent surge in memory prices, a hike now impacting the entire tech industry, from PCs to gaming consoles.
