J. Phys. D: Appl. Phys. 52 505304 (2019) This paper presents a study of bifurcation in the time-averaged dynamics of
TaO memristors driven by narrow pulses of alternating polarities. The analysis,
based on a physics-inspired model, focuses on the stable fixed points and on
how these are affected by the pulse parameters. Our main finding is the
identification of a driving regime when two stable fixed points exist
simultaneously. To the best of our knowledge, such bistability is identified in
a single memristor for the first time. This result can be readily tested
experimentally, and is expected to be useful in future memristor circuit
designs.
