World's three largest memory chipmakers sued in US over DRAM supply shift to AI memory
Seoul, June 30
A proposed US class-action lawsuit has been filed against the world's three largest memory chipmakers, according to a news report by The Korea Herald. The legal challenge accuses Samsung Electronics, SK hynix, and Micron Technology of restricting the supply of dynamic random-access memory, commonly known as DRAM, during their structural shift toward AI-focused hardware.
As per the news report, 17 plaintiffs, consisting of individual consumers and small businesses, filed the complaint in the US District Court for the Northern District of California last week.
The lawsuit alleges that these three companies, which control roughly 90 per cent of the global DRAM market, deliberately curbed the production of conventional memory products like DDR3 and DDR4 to redirect their manufacturing capacity toward high-bandwidth memory used in AI accelerators.
As per the news report, the plaintiffs claim this transition triggered a steep increase in DRAM pricing and drove up the retail cost of consumer electronics.
However, market experts and industry officials remained skeptical about the immediate fallout of the lawsuit, noting that the case is still in its infancy. The news report mentioned that the legal challenge faces a high burden of proof because the industry-wide transition toward HBM has been publicly documented for months.
The structural shift is widely recognized as a standard commercial reaction to the explosive global demand for AI infrastructure, rather than a coordinated effort to restrict supply.
As per the news report, the complaint itself acknowledges that total DRAM wafer capacity continues to expand globally. Industry projections show that global capacity will continue to rise through 2026, even as a larger share of that production is allocated specifically to HBM manufacturing.
Memory producers maintained that reallocating their production lines toward HBM became unavoidable as AI applications reshaped the broader technology landscape. These high-bandwidth chips generate significantly higher financial returns than legacy conventional DRAM products. Furthermore, HBM units require substantially more raw wafer capacity to manufacture, naturally tightening the supply of older memory lines.
The litigation is also projected to have minimal impact on short-term market pricing. US investment bank Jefferies forecast that DRAM prices will continue their upward trajectory through 2027 because AI-driven demand persistently outpaces overall supply growth, regardless of how the legal proceedings unfold.
"The case also differs from earlier DRAM antitrust cases in the 2000s, which involved explicit allegations of price coordination and output agreements. The current complaint centers instead on whether the industry's publicly announced shift toward HBM indirectly tightened the supply of conventional memory products," the news report said.
The legal filing arrives at a time when memory manufacturers are capitalising on one of the strongest market upcycles in recent history. Micron recently reported record quarterly financial results, while South Korean tech giants Samsung Electronics and SK hynix are both projected to post sharp earnings gains driven by sustained AI demand and elevated memory prices.

I'm an engineer in Bengaluru and I've seen how AI accelerators are gobbling up HBM capacity. The plaintiffs have a point about the supply squeeze for DDR3/DDR4, but proving collusion will be tough. These companies are just following the money. Sad for small businesses, but that's capitalism.
As someone who relies on DDR4 for my small server setup, I feel the pinch. But the article rightly says global DRAM capacity is still growing. The issue is allocation. I hope India starts some chip-making initiative—we can't keep depending on these few giants for everything. 🇮🇳
Hmm, I understand the plaintiffs' frustration, but this seems like a weak case. The industry shift to HBM has been obvious for months. It's like blaming a farmer for growing more profitable crops instead of the old ones. Prices will keep rising until supply catches up. Simple economics. 🤷♂️
Critics say this is just a normal market reaction, but look at Micron's record profits! Something stinks. If these three companies control 90% of the market, their decisions inevitably affect prices. I hope the US court digs deeper. Indian consumers are also paying more for laptops and phones now. 😤
I work in the memory supply chain, and this transition is real. HBM production uses way more silicon per chip, so naturally less capacity for old DRAM. The case might fail because it's about structural change, not collusion. But I wonder: will AI infrastructure benefit everyone or just
