Abstract: | We suggest and experimentally demonstrate a chaotic memory resistor (memristor). The core of our approach is to use a resistive
system whose equations of motion for its internal state variables are similar to those describing a particle in a multi-well
potential. Using a memristor emulator, the chaotic memristor is realized and its chaotic properties are measured. A Poincaré
plot showing chaos is presented for a simple nonautonomous circuit involving only a voltage source directly connected in series
to a memristor and a standard resistor. We also explore theoretically some details of this system, plotting the attractor
and calculating Lyapunov exponents. The multi-well potential used resembles that of many nanoscale memristive devices, suggesting
the possibility of chaotic dynamics in other existing memristive systems. |
