Sun and Unisys have jointly filed a lawsuit against several major computer memory chip makers seeking compensation for alleged price fixing.
The two computer makers individually filed lawsuits against the companies earlier this year but have now brought the cases together in the U.S District Court for the Northern District of California, according to a Friday court filing.
The complaint names South Korea's Hynix Semiconductor, Infineon Technologies of Germany, Japan's Elpida Memory and Mitsubishi Electric. Taiwan's Mosel Vitelic and Nanya Technology, and U.S and European units of some of the companies.
The lawsuit is one of several filed against DRAM makers after the U.S Department of Justice (DOJ) began an investigation into price fixing in 2002. That has already seen a number of guilty pleas by companies and executives, and fines have been levied against some DRAM makers.
Last year Samsung was ordered to pay a $300 million criminal fine and Hynix agreed to pay $185 million. Infineon paid a $160 million and Japan's Elpida agreed to pay a $84 million fine.
