Nantero's 'universal memory,' featured in MIT Technology Review's 2005 Breakthrough Technologies list, used carbon nanotubes intended to replace flash memory, random-access memory, and hard disk drives, but tiny variations in nanotube arrangement caused errors when the company tried to manufacture it at scale.

Notes on verification

Core claim about Nantero's universal memory goal and its scaling difficulties is confirmed by the original 2005 MIT Technology Review piece and corroborated by multiple trade-press sources (IEEE Spectrum, EE Times) over years. The specific phrasing about 'tiny variations in nanotube arrangement' causing errors is a reasonable paraphrase of documented purity/uniformity control issues, though not a verbatim technical description.
