Recent progress and challenges for relay logic switch technology

Abstract

The energy efficiency of CMOS technology is fundamentally limited by transistor off-state leakage (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OFF</sub> ). Mechanical switches have zero I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OFF</sub> and therefore could be advantageous for ultra-low-power digital logic applications. This paper discusses recent advancements in relay logic switch technology and current challenges which must be addressed to realize its promise.
