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."
That's what they said about transistors.
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.

Yeah, I bet your father said that when Intel produced their first 1024x1 ram chip. Pff... fuckin pie in the sky that was, integrated circuit RAM. They sure wasted their time; It never did become widely available at a decent price, as I recall.
Woops, gotta go. Sense amplifier on my core is drifting out of alignment.
