IBM hits terabit speeds with new chip technique2010-12-02 09:33 by DanielaTags: IBM, chip, CMOS
IBM has developed a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling data transfer using pulses of light. The CMOS Integrated Silicon Nanophotonics technology delivers a ten-fold improvement in integration density compared to current manufacturing techniques, says IBM, resulting in smaller, faster and more power-efficient chips. Indeed, with the new technology, a single transceiver channel with all accompanying optical and electrical circuitry occupies only 0.5mm2. The development will provide a big boost to the company's Exascale computing program, which is aimed at developing a supercomputer that can perform one million trillion calculations — an Exaflop — in a single second. That would make it around a thousand times faster than the fastest machine today. Read more -here-
