The thought of introducing filthy carbon nanotubes into an ultra-sensitive fab has blocked the rise of so-called NRAM or Nano Random Access Memory. Thanks, however, to a refined cleansing process and relentless browbeating start-up Nantero thinks it has mainstream semiconductor players close to giving NRAM a try.
Nantero has attracted the attention of some big name tech players, including HP, LSI and ON Semiconductor. These companies are either experimenting with NRAM in their R&D labs or actually trying to produce NRAM chips.
The Feds have a lot of interest in NRAM because of its longevity and density. Flash, while glorious, does degrade over time as insulators wear down due to charge fluctuations. Memory loss on a satellite or weapons system can be a real pain.
So I think NRAM will have a radiation hardened and endurance niche.
