Researchers Say New Chip Breaks Speed Record

Researchers at I.B.M. and the Georgia Institute of Technology are set to
announce today that they have broken the speed record for silicon-based
chips with a semiconductor that operates 250 times faster than chips
commonly used today.

The achievement is a major step in the evolution of computer semiconductor
technology that could eventually lead to faster networks and more powerful
electronics at lower prices, said Bernard Meyerson, vice president and
chief technologist in I.B.M.'s systems and technology group. He said
developments like this one typically found their way into commercial
products in 12 to 24 months.

The researchers, using a cryogenic test station, achieved the speed
milestone by "freezing" the chip to 451 degrees below zero Fahrenheit,
using liquid helium. That temperature, normally found only in outer space,
is just nine degrees above absolute zero, or the temperature at which all
movement is thought to cease.

At 500 gigahertz, the technology is 250 times faster than chips in today's
cellphones, which operate at 2 gigahertz. At room temperature, the chips
operate at 350 gigahertz, far faster than other chips in commercial use
today.

Mr. Meyerson compared the achievement to the development of the chips used
in Wi-Fi networks. It was not until the semiconductor technology used in
those networks was produced with silicon that wireless networking become
affordable for consumer applications.

Dan Olds, a principal at the Gabriel Consulting Group, a technology
consulting firm in Portland, Ore., said the development was significant
because it showed that the chip industry had not yet reached its upper
limits. "There's been talk that we've started to hit the physical
limitations of chip performance," he said. "The news here is that we're
not coming anywhere near the end in what processors are capable of."

Mr. Olds cautioned, however, that the technology was far from finding its
way into commercial products any time soon, considering the performance
leap it represents. Today's performance-hungry computer buyers, for
example, are buying machines operating at about three gigahertz, he said.

John D. Cressler, a professor in Georgia Tech's School of Electrical and
Computer Engineering and a researcher at the Georgia Electronic Design
Center, said the work "redefines the upper bounds of what is possible"
using silicon-germanium.

The research group included students from Georgia Tech and Korea
University in South Korea, and researchers from I.B.M. Microelectronics.
The results will be reported in the July issue of the technical journal
IEEE Electron Device Letters.

Oh dear, a lot of deep space objects are going to be terribly upset to
discover they have to stop moving at 0K. 8.

While that sentence may be misleading AFAIK, nothing can ever reach
0K/absolute zero. Perhaps you misunderstood the sentence.

The temprature reached was NOT 0K (which is not possible to reach). The
temperature was 9K which as they say is normally only found in outer
space.

Umm, no the temperature being discussed was 9F above absolute zero. I
think GSV's point was that the article mangles the result by a combo of
just regular journo-methods and the vulgarisation thought necessary to
present in terms which the American masses can grasp.
