3-D Nanoarchitectures With Carbon Nanotube Mechanical Switches for Future On-Chip Network Beyond CMOS Architecture

We have proposed 3 nanoarchitectures with carbon nanotube-based nano-electromechanical systems (CNT-NEMS) switch with a floating gate. It is shown that logic based on them has the potential to replace CMOS using process technology of less than 45 nm. Furthermore, CNT-NEMS-based 3-D circuits realize extremely high bandwidth of over 10 petabyte/s with very low latency of less than several 10 ps. The most effective applications are 3D on-chip crossbar bus and future on-chip network, which will largely determine the performance of future microchips. The performance of 3-D on-chip crossbar based on CNT-NEMS is also compared with that based on CNT-transistors.
