This is an interesting implementation of the memristor, but I still think the real breakthrough will be in the two state memristor [1]. Once memristor fabrication technology is mature, we are going to see a massive paradigm shift away from the Von Neumann architecture.

All the details are in the linked video by HP's Stan Williams. Definitely worth a watch if you're interested in the future of computing

1. https://www.youtube.com/watch?v=bKGhvKyjgLY (start at 38m for future computing implications)

EDIT:

Another video [2], but a bit more in depth. Recommended if the material in the first was a bit confusing as Stan was short on time to explain some of the details.

he doesn't seem to talk about the end of the Von Neuman architecture. Explain that part?

Start here, around the 38 min mark:

> Stan Williams of HP Labs gave a talk recently at Rice Any link?

Here is the abstract of the talk. There was a video made, but I don't see it online yet. http://www.k2i.rice.edu/EventsList.aspx?EventRecord=23375

Managed to find it here: https://mediacosmos.rice.edu/app/plugin/embed.aspx?ID=vVUTzF...

For example, the largest unsigned binary 64-bit ­integer—18,446,744,073,709,551,615— could be held in 20 bits instead of 64. This should read "could be held in 20 digits instead of 64 bits."

If "bit" is a portmanteau of "binary digit", wouldn't the analogue in a senary[1] number system be a "sit"?

Assuming they work out performance and other engineering issues, could this be used to implement something like qubits?

No, you can think of a qubit as a unit vector in the complex plane. It can have two real values, but also all kinds of complex values. Computing with a qubit is rotating the vector around, measuring it collapses its imaginary state to a real state. The probability which state you get depends on the rotation at the time of the measurement.

thanks very much for this! had been looking for some time for a quite recent Williams talk
