Carbon Nanotube RAM (CNT RAM)

Carbon nanotubes (CNTs) have great potential as the basis for memory chips. their small size and unique dimensionality allows for interactions between their electrical and mechanical properties which can be used to design fast, dense, and non-volatile data storage devices.
Whilst many CNT-based memory designs have been proposed, the difficulty in producing the nanotubes in sufficient purity and quality, and with integrating the nanomaterials with current semiconductor fabrication techniques, has prevented their widespread adoption.

Figure 2. Carbon Nanotubes have unique electronic properties that could be used to make highly efficient, fast, non-volative memory chips. However, there are many challenges in bringing the technology to market - mainly manufacturing the nanotubes in high enough purities.
