The terse statement by Samsung confirmed that the funds were being set aside on behalf of its U.S. unit, Samsung Semiconductor. Korea-based Samsung is the world's largest computer-memory manufacturer.
"The outcome of this matter cannot be predicted at this time," Samsung Electronics said in a statement. "The company is unable to comment on an ongoing government investigation."
In addition to the U.S. Justice Department, the European Union's regulatory agency is investigating alleged price-fixing in DRAM memory. In September, Germany's Infineon Technologies AG paid $160 million in connection with the price-fixing investigations and agreed to help investigators.
Previously all parties being investigated, including Samsung, denied any wrongdoing in memory pricing.
