Samsung and its US subsidiary Samsung Semiconductor have agreed to plead guilty and pay a $300 million fine for participating in an "international conspiracy" to fix prices on DRAM (dynamic RAM), the US Department of Justice (DOJ) announced Thursday.

Samsung's fine is the second largest criminal antitrust fine in US history and the largest criminal fine since 1999, the DOJ said.

Never again

Resolving the investigation was "paramount" to Samsung, said Chris Goodhart, the company's director of marketing communications. The settlement will not affect Samsung's day-to-day operations, she said in a statement.

"Samsung is strongly committed to fair competition and ethical practices and forbids anticompetitive behaviour," Goodhart added.

The DOJ filed a one-count felony charge against Samsung Thursday in US District Court in San Francisco. Between April 1999 and June 2002, the South Korean company and its subsidiary conspired with other DRAM manufacturers to fix prices of DRAM sold to PC and server manufacturers, the DOJ said.

Computer makers affected by the price-fixing scheme included: Dell, Compaq, HP, Apple, IBM and Gateway, the DOJ said.

Tinfoil hats all round

Under a plea agreement, which must be approved by the court, Samsung has agreed to cooperate with the DOJ in its continuing investigation of other DRAM producers, the DOJ said.

Samsung is charged with contributing to the conspiracy by communicating with competitors about the prices of DRAM to be sold to some customers and then agreeing to charge the agreed-upon prices, the DOJ said.

With Thursday's announcement, three semiconductor companies and five people have been charged in the DOJ's ongoing antitrust investigation into price fixing in the DRAM industry. So far, the DOJ has collected more than $646 million in fines in the investigation.

Naughty, naughty, naughty

In May 2005, South Korean manufacturer Hynix Semiconductor agreed to plead guilty and was sentenced to pay a $185 million fine. In October 2004, German manufacturer Infineon Technologies pleaded guilty and was sentenced to pay a $160 million fine.

In December 2004, four Infineon executives pleaded guilty to the DRAM price-fixing conspiracy. The four Infineon employees served prison terms ranging from four to six months and each paid a $250,000 fine.

In December 2003, the DOJ charged Alfred Censullo, a regional sales manager with Micron Technology, with obstruction of justice. Censullo pleaded guilty and said he withheld and altered documents related to a grand jury subpoena served on Micron in June 2002. Censullo was sentenced to serve six months of home detention.
