While there have been no shortage of nanotech related approaches to the non volatile memory market, competing with the likes of Samsung never going to be easy.
Samsung sold almost 4 billion dollars worth of flash memory in 2004, and are already looking ahead at nanotube based memory as this article in EE Times shows. What this means for, or how if differs from the technology used by Nantero is still unclear, but it does indicate clearly that if anyone is thinking of disrupting a $4 billion market, the current leaders may fight back.
Good overview. No doubt that Samsung will beat any start-up quickly.
