All electrical circuits need a voltage source to function. This source is used to bias the circuit. Where and how can the voltage source be placed in a two-component circuit made of two dipoles like a capacitor or a coil and a memristor?
The memristor is a device different from the other three two-terminal elements.

Dear Marco,
Thanks for your answer to my question. I have gone through the links and read carefully all these documents. But still, my question remains unanswered. The Memristor is definitely a two-terminal device according to all the publications from Professor Chua and other authors, even if it is different from the three previous fundamental elements in the way that it has a memory. Since the Memristor is a two-terminal device, it seems to me physically impossible to imagine a two-component circuit made of a Memristor in parallel with either a capacitor or an inductor as it appear in some recent publications (Muthuswamy B., Przybylski A., Feilbach C. and Mossbrucker J. Two Element Chaotic and Hyperchaotic Circuits, 4th International Interdisciplinary Symposium on Chaos and Complex Systems Antalya, Turkey, April 30th 2012.
Pham, V.-T., Buscarino, A., Fortuna, L. and Frasca, M. Simple Memristive Time-Delay Chaotic Systems. Int J Bifurcat Chaos 2013;23(4):1350073–81). The question is: How will the circuit be biased? The Analog simulation of different Memristors is made of operational amplifiers among other components. Such simulations show always that the imagined two-component circuit is biased through the operational amplifiers imbedded in the overall circuit mimicking the Memristor! In a real Memristor, would there be Operational Amplifiers?
Moreover, it seems difficult to me (or may be unrealistic) to imagine a delay circuit inside the Memristor (Pham, V.-T., Buscarino, A., Fortuna, L. and Frasca, M. Simple Memristive Time-Delay Chaotic Systems. Int J Bifurcat Chaos 2013;23(4):1350073–81) because, according to Strukov et al., the Memristor could not be found before 2008 because it can only exist in nanostructures, meaning that it is really very small, while attempts to realize it physically was done in bigger structures (Strukov DB, Snider GS, Stewart DR, Williams RS. The missing memristor found. Nature 2008;453:80–3). This rises the following question: Is something hidden around the Memristor? I believe there are still many questions around the experimental realization of chaotic two-component circuits involving the Memristor. Discussions about these points hail the scientific community.
