Crack-Based Complementary Nanoelectromechanical Switches for Reconfigurable Computing

Reconfigurable computing (RC) enables hardware to operate with the flexibility of software. This is achieved by programming the interconnections between logic blocks. In this study,we exploited crack-based complementary nanoelectromechanical (CNEM) switches to construct energy-efficient and high-density RC. Our proposed device integrates the advantages of ferroelectric and NEM switch, such as nonvolatility, a quasi-zero OFF-state leakage current and a low operating voltage. Complementary switching enables our device to operate as a CMOS inverter in a very simple manner. Thus, this device can readily implement programmable routings. The voltage required to maintain the routings is not needed, leading to significant saving in static and dynamic power consumption. In addition, the fundamental AND, OR and NOT logic gates can be condensed into a single CNEM switch device to implement the reconfigurable logics, thereby reducing chip area and energy dissipation. We believe that our device paves the way for development of energy-efficient electronics.
