So, What Was That Memory Technology Again?
Many scientists believe it will be possible to use carbon nanotubes (CNTs) for system memory in the near future and complex logic farther out (see "Back To Nature For Next-Gen Semis"). For example, professor Qing Jiang of the University of California at Riverside and his research partner Jeong Won Kang discovered a multiwalled CNT structure that consists of an outer tube and inner tube that can oscillate at a high frequency with a voltage stimulus. The inner tube's position indicates the nonvolatile logic state.
