Processor, heal thyself

— 11:17 AM on July 31, 2004

Yesterday, the wraps were taken off "eFuse", an autonomous chip technology developed by IBM. This technology turns the tables on electromigration, a processor's natural enemy, by using it to trip fuses on the processor die, allowing the chip to actually detect/work around flaws in the chip, and adjust its performance/power consumption. IBM technologist Bernard Meyerson explains that "eFuse reroutes chip logic much the way highway traffic patterns can be altered by opening and closing new lanes." Big Blue has already begun production of eFuse processors in chips featuring its Power architecture.
