MRAMs to Power Cell Phones

Spin i Reversed Below the EquatorThe Memory Guy today became aware of a significant breakthrough in magnetic memory technologies (MRAM) that could prove to be a big bonus for mobile applications.  These memories could be used to generate power as well as to store data.

Scientists have only recently become aware of an oversight stemming from the fact that nearly all spin magnetics research has been performed in the northern hemisphere.  Just as the water in a drain rotates counterclockwise in the northern hemisphere but clockwise in the southern hemisphere, the Coriolis Effect dictates that magnetic spin has the opposite sense above the equator as below.

This surprise finding was made when researchers from Stüdpfalz University of Blindman’s Bluff, Iowa, brought samples of an STT MRAM they had developed to the Townsville City Metropolitan University in Queensland, Australia, where researchers have been producing similar magnetic memories below the equator.  Until that moment neither team had thought to question the Continue reading “MRAMs to Power Cell Phones”
