FinFET CMOS logic gates with non-volatile states for reconfigurable computing systems

摘要

A series FinFET based non-volatile logic gates with multiple logic functions defined by embedded non-volatile states are proposed for the first time and demonstrated in advanced CMOS technology platform. The device channels in the proposed CMOS logic gate is controlled by a metal floating gate coupled by slot contacts uniquely available in the FinFET process employed in this study. The new logic gate with non-volatile states only enable reconfiguration ability in a Boolean computing unit at a gate level aimed for adaptive and specialized systems in the AI era. Furthermore, the extended applications in tunable ring oscillators for multi-functional IOT modules are successfully demonstrated in this study.
