Power/Performance Bits: Feb. 5


Photonic-magnetic memory Researchers at the Eindhoven University of Technology (TU/e) have developed a hybrid photonic-magnetic memory device that takes advantage of the speed of optical writing and stability of magnetic drives. "All-optical switching for data storage has been known for about a decade. When all-optical switching was first observed in ferromagnetic materials - amongst the mo... » read more

Power/Performance Bits: Nov. 10


Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more
