A class-action lawsuit filed on June 25 in a U.S. court has named Micron Technology (MU), Samsung Electronics, and SK Hynix in an anti-trust case over alleged DRAM price fixing. The claim is that these three companies, which control most of the global DRAM market, cut back production of older DDR3 and DDR4 chips while shifting focus to AI-focused High Bandwidth Memory (HBM).
According to the lawsuit, that move was meant to push prices higher, not just follow demand. DRAM prices have jumped about 700% since 2022.
