Silicon oxide, not silicon dioxide. If deliberately oxygen-deficient, that's a special requirement, not regular process sio2.

There is a Nano Lett paper on this. The voltage is key. Begs comparison to flash programming.

It's time to add a new word in the dictionary - "Memristors". It is great to know that Rice University could prove the concept design of ReRAM using silicon instead of titanium. But I'm not certain reading this article whether Rice could really achieved the performance what HP might have achieved using titanium. 10,000 read/erase/write cycles is quite low compared to the current Flash parts, correct? Again a question come to my mind: there are other new memory technologies such as MRAM/FeRAM etc are also going through commercialization cycle. Which one is going to win? Any thoughts?

Sanjib, I guess it depends on where the Flash is being used. For example 10,000 R/W cycles is considered standard for flash used in programmable logic.

10,000 cycles should also be adequate for memory keys and SD/SDHC/XD/etc. cards used in cameras.

A better and more exciting application for this technology is to enable the re-birth of analog computing. Imagine a filter that can be reconfigured or tuned in the field or during manufacturing. A great as digital processing is today, it could not match the performance of an analog solution. Think about an integrator and differentiator circuits alone. This would also provide the concept of non-volatile analog memory...WOW my mind is spinning wildly!!!

I think using this in analog computing is a great idea! Could we build an array of programmable resistors? We could then make use of those programmable resistors in analog circuits. Pardon me...I don't understand the device physics of Memristor quite yet and my comment could sound absurd to the experts in this field. But just trying to draw some more ideas from experts interested in "analog computing" topic.

The mechanism sounds similar to that described in Axon TC's "Programmable Metallization Cell" in which AgS forms a conductive path in a chalcogenide matrix. Axon claims 5 ns symmetric access times and is compatible with voltage and geometric scaling. I'm looking forward to this technology coming out of stealth. Wonder what Rice plans to do with it? Research in the resistive memory segment is showing a lot of promise, is simple, the arrays can be stacked for increased density, have good to excellent duration (some are nearly non-wearing) and are scalable in both voltage and geometry. Industry roadmaps are made of things like this...,

I'm not sure if this is the same mechanism as Axon's GeS devices but a quick check of the US Patent Office site reveals that there are already several issued patents on oxide-based devices, including silicon oxide. Are these guys late to the party or am I missing something here?

The power of memristors is more than memory. Per HP's comments, memristor is also capable of computing. That will be the killer application: memory+computing in 1 shot similar to human neurons.

Manny- I do not know if you are aware but there was a project at Harris Semiconductor (ca 1980) to use phase change memory (PCM) in the role you suggest, not during manufacture, but during in-flight operation. Without going into detail of the particular application, the idea was to very quickly repair in-flight an amplifier that had suffered from severe levels of radiation damage. The repair would bring the gain of the amplifier back to nominal by using the PCM as a switch to bring the different resistors and other components in and out of the feedback loop. The extreme radiation hardness of the PCM in all environments up to strategic levels made it an ideal candidate device for that application. Although the radiation hardness of the Rice ReRAM is not known, or more accurately I am not aware of it, a column of silicon nano-crystals in SiO2 would appear to offer radiation hardness in the same way that a column of degenerately doped tellurium crystals in a PCM.
