Judge Noël Wise denied Micron, Samsung and SK hynix's motion to dismiss a proposed class action alleging that they coordinated restrictions on DRAM memory supply. The court found the allegations plausible enough to proceed, rejecting the companies' argument that the suit merely repeated a 2018 antitrust case.

The 17 individuals and small businesses bringing the case cite parallel production cuts, a shift toward high-bandwidth memory and announcements winding down DDR4 production. They allege those moves contributed to shortages and price increases of as much as 500% in one year.

The chipmakers say they independently responded to the same market pressures. The ruling does not establish liability; they have until December 7 to respond to the complaint.
