Rambus Says Fraud Lawsuit Is Dismissed

Rambus Inc., a designer of high-speed computer memory chips, said a Delaware court dismissed a suit against the company, and that Toshiba Corp. will use a Rambus design in a new semiconductor. Its shares rose 4.2%.

The dismissal of the lawsuit followed a decision by a U.S. appeals court in January to throw out a jury’s finding that Rambus committed fraud while pursuing patents for high-speed memory chips that became an industry standard.

Rambus still faces fraud claims by the Federal Trade Commission. That trial is underway in Washington.

Shares of Los Altos, Calif.-based Rambus rose 77 cents to $19.16 on Nasdaq.
