Telescopic nanotubes aim to combine virtues of SRAM, flash

Abstract:
Random access memories require constant power to offer their fast access speeds, but can't be scaled to as small a size as slower nonvolatile flash memories. Now researchers believe they can combine the high-speed of RAM with the nonvolatility of flash by using telescopic nanotubes.

Ultra-dense nano-electro-mechanical system (NEMS) arrays could offer molecular sized memory cells that are as fast as RAM but nonvolatile like flash by harnessing concentric nanotubes that turn bits on and off by running current through the tubes to make the inner one stick out or stay inside the outer nanotube.

Professor Elena Bichoutskaia at the University of Nottingham is leading a study aimed at replacing silicon-based memory technologies with carbon-based concentric telescopic nanotubes that measure only a few nanometers in diameter. This NEMS approach uses the mechanical movement of nanotube telescoping in and out of concentric tubes to either contact or break contact with a molecular-sized electrode, thus combining the speed of RAM with the non-volatility of flash memory.
