Japanese scientists design fastest ICTokyo 02 January 2002 The world's fastest integrated circuit has been designed in Japan. This chip, which uses properties of a high-temperature superconductor, performs arithmetic operations 135 times faster than any most sophisticated computer available in the world this day.
The new integrated circuit has been invented by a team of scientists at the Tokyo research institute. It has a laminar structure where plates with a thickness of one-tenth of a micron are interspaced by insulators.
The device employs the effect of magnetism that occurs when the circuit cools to a temperature of 233 decrees Centigrade, or 40 degree above absolute zero.
Scientists of many countries had gripped with the problem of creating such integrated circuits, but nobody succeeded to increase their operating temperatures to above minus 269 degrees.
Japan's new product opens a way to designing a family of high-speed and energy-saving supercomputers and further development of the Internet. Computers based on such chip would use 46 per cent less energy as compared to present-day versions.
