Samsung, SK Hynix, Micron Sued in US over Memory Price Fixing
A new US lawsuit accuses Samsung, SK Hynix and Micron of colluding to restrict DRAM supply and phase out older standards like DDR3/DDR4 in favor of more profitable HBM, allegedly driving up memory prices for everyone from PC builders to cloud providers. Commenters debate whether current price spikes reflect illegal cartel behavior or simply surging AI demand and long fab lead times, while pointing to past DRAM price-fixing cases, weak antitrust tools against tacit collusion, and the risks of a three-player global oligopoly over such a critical component.
Historical context & prior cases
- Commenters recall past DRAM price-fixing scandals and fines, noting this “once a decade” pattern and prior US and EU actions.
- A 2022 US case was dismissed for lack of evidence of an explicit agreement, reinforcing how hard these cases are to prove.
Is there collusion now?
- Some believe current conditions don’t require collusion: AI demand is so extreme that high prices follow naturally.
- Others argue tacit collusion is likely: a small oligopoly can move in parallel on supply and pricing without leaving a paper trail.
- OpenAI’s large public memory-buy commitment is viewed by some as a “legal” public signal that made it easy for suppliers to raise prices in lockstep.
Market structure & barriers
- Only three major DRAM vendors control ~90% of supply, with long investment cycles and huge capex.
- High technical, IP, and tooling barriers make new entrants almost impossible in the short term; even large chip firms can’t easily pivot into DRAM.
- Some push back on calling RAM a mere “commodity,” emphasizing its extreme engineering complexity.
HBM and discontinuation of DDR3/DDR4
- The lawsuit claims the firms restricted DRAM supply under the pretext of shifting to HBM and dropping DDR3/DDR4.
- Many commenters see sunsetting DDR3 as normal, but are split on DDR4:
- One side: DDR4 is still widely useful and profitable; turning it off looks like herding customers into pricier DDR5/HBM.
- Other side: aftermarket DDR4 demand is niche vs datacenter/AI; fabs are rationally reallocating to higher-margin HBM/DDR5.
Legal standards & antitrust challenges
- Multiple comments stress that restricting supply is legal unless there’s an agreement among competitors; proving that agreement is the core challenge.
- Some advocate shifting antitrust law toward inferring collusion from outcomes (sustained high margins, no new entrants) rather than requiring “smoking gun” evidence.
- Others warn this risks punishing firms for not having “a crystal ball” in a boom–bust industry.
China, geopolitics, and alternatives
- Some see Chinese DRAM maker CXMT as the only realistic check on the “memory cartel,” even if it initially serves mainly China.
- Others worry about long‑term dependence on a state-backed competitor and note export controls and ASML’s limited capacity as structural constraints.
Consumer and ecosystem impact
- Many highlight knock-on effects: higher costs for PCs, consoles, embedded devices, and data centers, with smaller buyers crowded out by hyperscalers and AI labs.
- Others note that lawsuits often end in tiny class-action payouts and limited deterrence, given how small fines are relative to profits.
