A nanoscale random access memory (NRAM) memory chip based on carbon nanotubes under development by Nantero would have a theoretical capacity of 10 gigabits of data and would be non-volatile.

To simplify fabrication, Nantero applies the nanotubes randomly across the entire surface of a silicon wafer. It then uses existing lithographic equipment to etch away the nanotubes that are not in the correct alignment.
