Future IBM chips will be able to change themselves


Recommended Posts

NEW YORK -- Future microprocessors from IBM will optimize their performance by altering themselves, adding memory or removing unneeded bits of circuitry on the fly, the company's chief technologist said Wednesday.

The self-morphing chips, still in development, were disclosed as IBM revealed wide-ranging plans for the company's current generation of chips, the Power5.

Big Blue hopes to work with outside technology developers to make Power chips a flexible, widely used driver of several kinds of computing systems, from high-end corporate servers to video game consoles and handheld devices.

For decades, microprocessors have gotten ever faster by cramming more and more transistors onboard, but the physical limitations of the materials involved is making it harder to shrink the dimensions much further.

Instead of relying on continual improvements in chip speed, future chips must be more cleverly designed to combine more computing functions, said Bernard Meyerson, IBM's chief technologist. The self-altering chip is one means of achieving that.

Here's how it would work: Continually running electrical current through a tiny circuit can cause its materials to erode, as individual atoms get stripped and dragged away by the electricity. Eventually the metal breaks.

Chip designers got around the problem by carefully choosing a blend of metals. Now, Meyerson said, IBM has developed a way to make the metal erosion happen at will -- when software running the chip determines that part of the circuitry needs cutting or tuning.

I promise you this isn't an April fools joke. I read this as the top story of the Sun-times business section and then found the story on their site to post here. If anyone doubts me I can scan the article and post it.
