  At least you can try out a fictional one here: http://www.falstad.com/circuit/e-mr.html http://www.falstad.com/circuit/e-mr.html

  According to [1], RRAM is a form of memristor*. You can buy these at DigiKey [2]. However, I can't really think of a practical application. It's about 10x slower than (P)SRAM. [1] - https://en.wikipedia.org/wiki/Resistive_random-access_memory https://en.wikipedia.org/wiki/Resistive_random-access_memory [2] - https://www.digikey.com/products/en/integrated-circuits-ics/memory/774?k=reram https://www.digikey.com/products/en/integrated-circuits-ics/... > Leon Chua argued that all two-terminal non-volatile memory devices including ReRAM should be considered memristors. Stan Williams of HP Labs also argued that ReRAM was a memristor. However, others challenged this terminology and the applicability of memristor theory to any physically realizable device is open to question. Whether redox-based resistively switching elements (ReRAM) are covered by the current memristor theory is disputed.

  > (funny enough, doing the same at aliexpress yields a young kid's plastic ball ad, containing "Warning:Memristor") Happy Fun Ball may contain one or more memristors, and may or may not be sentient as a result. It is recommended to treat Happy Fun Ball with respect as a precaution.

  I went a step further a while back and emailed Digikey to see if they had any insight on memristor availability. This is what I got back: Thank you for contacting Digi-Key with your request about Memristor parts. While none of Digi-Key official supplies have any existing memristor parts available, there a few companies that have made experimental development chips available for sale. https://knowm.org/product/bs-af-w-memristors https://knowm.org/product/bs-af-w-memristors http://www.bioinspired.net/products-1.html http://www.bioinspired.net/products-1.html Seems like general availability of a real memristor is still a ways off - if at all.

      Heh, interesting. Not that all the saber-rattling about patent violations particularly makes me want to do business with Knowm.
