NEW YORK: International Business Machines, the world's biggest computer services company, built a semiconductor that runs 250 times faster than the average cell phone chip.
IBM researchers, working with the Georgia Institute of Technology, reached 500 gigahertz by freezing chips to 451 degrees below zero Fahrenheit, a temperature that occurs naturally only in outer space, the company said on Tuesday.
The chips may be used in business and defense systems. At room temperature, the semiconductors operate at 350 gigahertz.
Computer simulations suggest the chips, which are made of silicon and germanium on a 200-millimeter wafer, have the potential to work even faster than 500 gigahertz at room temperature.
