"Nanotube-based #NRAMs taking over the world soon," @EETimesEurope article.

Back in July 2000, the paper was laying the foundations for a bistable non-volatile RAM cell to be designed with a suspended Single Wall Carbon Nano Tubes (SWCNTs) crossbar array, switchable into well-defined Off and On states. The device being designed in such a way that each state represent a potential energy minimum (a balance between elastic energy in the Off state and the van der Waals energy in the On state), switched by charging the nanotubes to produce attractive or repulsive electrostatic forces. NRAM switch working principle (left) and implementation (right). In his paper describing the 1 transistor SWNT NRAM cell, Rueckes had established possible switching speeds up to 100GHz for a 20nm device, extrapolating this to 200GHz operation for a cell designed at the 5nm node (owing to the smaller effective mass of the moving CNTs). Other claims are that the NRAM operat...
