South Korean chip and electronics maker Samsung will plead guilty to allegations of price fixing and pay a fine of $300 million in a pact reached with the Justice Department. Samsung's plea and fine resulted from a government probe of dynamic random access memory chip makers. Other DRAM companies, South Korea's Hynix and Germany's Infineon ( IFX), have already paid fines. The U.S. government said the companies had conspired over a roughly three-year period ending in June 2002 to fix the prices of memory chips. Among the companies said to be hurt by the plot were some of the biggest names in technology, including Dell ( DELL), Hewlett-Packard ( HPQ), Apple ( AAPL) and IBM ( IBM).
