The world’s three biggest memory makers are facing a proposed antitrust lawsuit accusing them of coordinating RAM supply and pricing to push memory costs higher.
The case, filed as Garciaguirre et al v. Samsung Electronics Co., Ltd. et al in the U.S. District Court for the Northern District of California, targets Samsung, SK hynix, and Micron Technology. Together, the three control the vast majority of the global DRAM market.
The complaint alleges that the companies coordinated their pivot toward high-bandwidth memory (HBM) in a way that squeezed supply of older DDR3 and DDR4 chips, driving prices up for PC builders, device makers, and consumers. The allegations are unproven and the companies haven’t publicly responded.
HBM is the premium stacked memory powering AI accelerators like Nvidia’s data center GPUs. Demand has exploded thanks to massive orders from hyperscalers and AI firms, and it carries far higher margins than commodity DRAM.
The lawsuit claims the three manufacturers used the HBM shift as cover to cut output of conventional memory. Plaintiffs reportedly point to recent price hikes across the tech industry as evidence of the downstream damage.
There is, however, a clear alternative explanation. Wafer capacity is finite, HBM is more profitable, and AI buyers are willing to pay almost anything. Shifting production toward the highest-margin product is also just standard business behavior, which is the defense the companies will likely lean on.
This isn’t the first time these three names have appeared in an antitrust file. In the 2000s, the U.S. Department of Justice secured guilty pleas in a major DRAM price-fixing conspiracy, with hundreds of millions of dollars in fines and prison time for some executives. Samsung, SK hynix (then Hynix), and Micron-linked entities were all caught up in that era of enforcement.
What gamers should care about
RAM prices have been climbing fast, and the squeeze hits everything from DIY memory kits and gaming laptops to handhelds, prebuilts, and future console revisions. Valve has already publicly complained about tough negotiations with memory suppliers, a reminder that even well-known hardware names are small fish next to Amazon, Microsoft, Google, and Meta when it comes to chip contracts.
The case is at an early stage. To survive a motion to dismiss, plaintiffs will need to show plausible signs of actual coordination rather than just three companies independently making the same profitable decision. If it clears that bar, discovery could force the manufacturers to hand over internal pricing documents, supply plans, and executive communications.
