Narrator: This is Science Today. The computers of tomorrow could rely on magnetic microprocessors that use much less energy than today's silicon-based microprocessor chips. Engineers at the University of California, Berkeley, are using nanomagnets to build magnetic memory and logic devices that may set the stage for the first magnetic computer.
Bokor: Magnetic computers would use no current flowing through the wires. It would just be based on little magnets flipping. ... You can think about these magnets just like the ones you play with on the table top except they're scaled way down into the size scale of nanotechnology. And we're using these little magnets to interact with each other to perform information processing or logic function.
Narrator: Electrical engineer and computer scientist Jeffrey Bokor says once this magnetic logic technology is fully developed, it would pave the way for much more powerful and energy efficient computer devices.
Bokor: The products that would be made using this fundamental technology would pack a lot more information processing capability, only with maybe a factor of 10 or more less power.
