The First Ever Real Bistable Memristors—Part I: Theoretical Insights on Local Fading Memory

It has been recently shown that a current-controlled extended memristor may exhibit bistable steady-state behavior under dc as well as ac periodic stimuli. This brief employs standard techniques from the nonlinear dynamics theory as well as circuit and system theoretic concepts to explain the origin of the asymptotic bistable behavior, which is the signature of a local fading memory capability. Part II derives the first real memristor featuring similar complex dynamics.
