Hynix Semiconductor has agreed to plead guilty to DRAM price-fixing, and is willing to pay a $185m (£102.7m) fine to settle a competition violation case brought by the US Department of Justice.
The Hynix settlement is the latest in a series of actions brought by the DoJ against the dynamic random access memory industry for allegedly operating a cartel.
Hynix had been charged with price-fixing between summer 1999 and summer 2002. The DoJ charged that the company's actions had harmed major PC makers, including Dell, HP, IBM and Apple.
Despite sales of PCs declining during the period in question, Hynix hiked the price of its products, and PC makers started to raise questions about the big increases.
The DoJ launched an investigation into alleged price-fixing in 2002.
Infineon and others have also been accused of taking part in a cartel to drive up DRAM prices.
Infineon pleaded guilty last year and agreed to pay a $160m fine.
