A former executive at a Japanese computer chip maker is the latest person to agree to plead guilty in a global Justice Department price-fixing probe, the government said Thursday.

D. James Sogas of Burlingame, Calif., ex-vice president of sales for Elpida Memory, agreed to plead guilty to violating the Sherman Act. He agreed to serve a seven-month prison term and pay a $250,000 fine if the plea deal is approved by a federal judge.
