Carbon Nano tube- Based Nonvolatile Random Access Memory
Carbon nanotubes exhibit outstanding structural, mechanical and electronic properties, which make them ideal wires for molecular electronics. Nanotechnology propose using nano-scale carbon structures as the basis for a memory device. Recent developments in nanodevices presented a new approach for a highly integrated, ultrafast, nonvolatile Random Access Memory (RAM) based on carbon nanotubes.
A single-wall carbon nanotube would contain a charged buckyball. That buckyball will stick tightly to one end of the tube or the other. The bit value of the device is assigned depending on which side of the tube the ball is. The result is a high-speed, non-volatile bit of memory. A number of schemes have been proposed for the interconnection of these devices and examine some of the known electrical issues.
