The Fourth Fundamental Passive Circuit Element

[gravityblock]

HP abandoned memristors and took it off their roadmap for their super computer "The Machine".  Everyone else has been focusing on ReRAM but I think the jury is still out on if this is just another memristor variant (HP wants to say it is so the millions they flushed down the drain on Memristors didn't go to waste). Intel is now focusing on 3D Xpoint although very little is known about it and based on what has been released it looks like another CBRAM variant that is apparently 1000x NAND and higher density then DRAM.

Two letters for you at this time:  AI

Not sure memristors have the synaptic capabilities everyone was hoping for and I don't know any research teams focused on neuromorphic (cognitive) computing who are seriously considering memristors in the AI field.  But you can prove me wrong in 10 years.

No, I'll prove you wrong right now, and not in 10 years.  You are worst than wrong as always, lol.

Researchers have developed a new kind of neural circuit that uses memristor technology to replicate the complex human brain. The "intelligent" circuit was able to perform some human tasks that computers usually struggle at, such as image classification (see image and reference link below).

Here's a video demonstration in how a coherer can be configured as a memristor.

The basis for the operation of the coherer is that the metal particles (beads in this case) cohere or cling together and conduct electricity much better after being subjected to radio frequencies. The radio signal from the antenna is applied directly across the coherer's electrodes. When the radio signal from a "dot" or "dash" came in, the coherer would become conductive. The coherer's electrodes were also attached to a DC circuit powered by a battery that created a "click" sound in earphones or a telegraph sounder, or a mark on a paper tape, to record the signal. Unfortunately, the reduction in the coherer's electrical resistance persisted after the radio signal was removed. This was a problem because the coherer had to be ready immediately to receive the next "dot" or "dash". Therefore a decoherer mechanism was added, to tap the coherer, mechanically disturbing the particles to reset it to the high resistance state.

Coherence of particles by radio waves is an obscure phenomenon that is not well understood even today. Recent experiments with particle coherers seem to have confirmed the hypothesis that the particles cohere by a micro-weld phenomenon caused by radio frequencies flowing across the small contact area between particles. The underlying principle of so-called "imperfect contact" coherers is also not well understood, but may involve a kind of tunneling of charge carriers across an imperfect junction between conductors.

Thank you Gravock for the interesting posts.  I am surprised you don't have a few more people commenting about the information you have shared.  I am not sure how I would make use of the memristor but I am old enough to know that any knowledge gained may come in handy at a later time.  It is also interesting that this simple device can be made at home pretty easily.  Do you have any simple applications for it since I don't think I will be building any neural computers any time soon.
