How past informs future of magnetic computers

 

Narrator:       This is Science Today. Engineers at the University of California, Berkeley, are drawing on the technological advances of past decades in an effort to build the magnetic computers of tomorrow. Such magnetic computers would use nanomagnets for information processing.

Bokor:            It dates all the way back to the late '60s, early '70s when computer memories were made from tiny magnetic cores. And people who were engineering these core memories actually had the ideas for doing magnetic logic way back then.

Narrator:       Researcher Jeffrey Bokor explains that interest in magnetic logic technology dwindled when silicon-based memory replaced core magnetic memory in our computers. 

Bokor:            Now magnetic technologies have been coming into the labs because our conventional silicon memories are running up against limitations. We're now seeing magnetic memory come into the market as an alternative to our flash memory that we use in our cameras and our smart phones. So once that technology began to come into the market, the ideas of doing magnetic logic got revived.
