Sun has made good on its promise to slap DRAM manufacturer Hynix with another price fixing lawsuit, which it made in April when a federal judge dismissed a joint complaint with Unisys.

Judge Phyllis Hamilton threw out that case, ordering Sun to come up with more evidence by 4 May or quit its whinging. The IT giant went back to its legal bunker and prepped another complaint, which it laid down on deadline day.

The saga goes back years and Hynix, along with other RAM makers, admitted cartel behaviour to the US Department of Justice in 2005, and was hit with a $185m fine. The scandal has engulfed almost the entire RAM industry.

Sun says the new complaint has more detail about its purchasing and delivery arrrangements with Hynix. It adds new allegations that Hynix conspired to fix bidding processes and tied employee rewards to the success of the cartel. ®
