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.
Although existing technologies use magnetic fields to store information on small chips called MRAMs, this is the first application to produce a chip that can process digital information in addition to storing it.
