A class-action antitrust lawsuit filed in California accuses Samsung Electronics, SK Hynix, and Micron Technology of colluding to fix prices and restrict supply in the DRAM memory chip market.

The complaint alleges the companies coordinated production shifts toward AI-focused high-bandwidth memory, limiting older chip output and driving prices up by as much as 700% since 2022.

The case comes amid a global memory chip shortage fueled by surging AI demand, which is raising costs for electronics manufacturers and consumers.

Industry observers warn the shortage could also affect sectors like automotive and medical device production due to higher input costs, Money Wise has reported.

Consumer memory prices have reportedly surged dramatically, with some RAM kits increasing severalfold over recent years.
