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.
Indeed, that's what they said about transistors. Even in the early 80ies, we learnt in school that tubes were the non plus ultra and that transistors had an uncertain future!! A few years later, tube production was stopped everywhere.
