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

Manufacturing Bits: Jan. 28


Spintronics gains traction The field of spintronics is gaining interest. The technology could enable a new class of spin-based devices, which combine the switching speeds of logic and the non-volatility of memory. Controlling the magnetism by means of electric fields is the key for future devices, but the ability to switch ferromagnetism technology at room temperature is challenging. Helmho... » read more
