New Speed Record For Magnetic Memory

Iddo Genuth writes "An experiment performed at the Physikalisch-Technische Bundesanstalt (PTB) in Germany has uncovered that a spin-torque switching of a nanomagnet is as fast as what is permitted according to the fundamental laws of physics' limit. This method of switching, also named ballistic switching, could allow for increased speeds in future non-volatile magnetic memories."

By using the ballistic spin torque reversal, potential MRAMs could be programmed by current pulses quicker than 1 nanosecond and subsequently, achieving write clock rates well above 1 GHz. Thus, high-density and non-volatile memory executing at the clock rates of the fastest volatile memories were enabled.
