InterTwined

As transistor-based microchips hit the limits of Moore's Law, a group of electrical engineers at the University of Notre Dame has fabricated a chip that uses nanoscale magnetic "islands" to juggle the ones and zeroes of binary code.
Computers using the magnetic chips would boot up almost instantly. The magnetic chip's memory is nonvolatile, making it impervious to power interruptions, and it retains its data when the device is switched off.
