A class action lawsuit was filed on June 25 in the U.S. District Court for the Northern District of California (case 3:26-cv-06345) against Samsung, SK Hynix, and Micron, alleging coordination to reduce DDR3 and DDR4 output while shifting to HBM. The three firms produce nearly all global DRAM chips, and RAM prices have reached record highs. Interactive price data for DRAM, NAND flash, and HBM is publicly available.
