In a press release, Tokyo-based Sony said it "has received a subpoena from the U.S. Department of Justice (DOJ) Antitrust Division seeking information about its static random access memory (SRAM) business. Sony intends to cooperate fully with the Justice Department in what appears to be an industry-wide inquiry."
The news would add to the regulatory headaches faced by Sony. Earlier this month, the company entered into a formal recall agreement with the U.S. Consumer Product Safety Commission in connection with its defective laptop batteries - part of a worldwide battery pack recall that will cost Sony about $430 million, the company said earlier this month.
No additional details were available immediately about the Justice Department's investigation. Last year, Samsung pleaded guilty and agreed to pay a $300 million fine in connection with DRAM price fixing in a separate Justice Department anti-trust matter.
