Ok, hold on guys. Was just pointed out to me, memristance means the resistance is a function of the charge that has passed through. In that case, this would not make a good resistance-based memory, as each time you read it, you are passing charge through it!
It's true these are resistance-based technologies, but ReRAM or RRAM is usually referring to those systems where the conduction path effectively disappears and reappears within a normally expected insulator. With MRAM you always have tunneling current density. With PCM you have a semiconductor changing resistance.
thank you Junko for straightening memristor story...this story is very intriguing...commercializing a completely new technology in 2-3 years sounds almost impossible, this is not a process shrinkage, new gate material, or new dielectric stack, this is something completely new and not well understood, there is not a single electronic textbook that covers this 4th missing electronic component (after R, L, C)...hoping that you can derive millions in revenue at 22nm node seems like a big stretch to me, I am putting my money on flash ;-)...Kris
Thanks for the background. Yet, since it is so basic and universal, maybe every device in use today already incorporates some memristor, if unknowingly? The fact that Flash memory needs wear leveling, for example?
I am curious about financial details. HP Labs may be looking at commercialization activities as a way to finance their long term research goals.
I am left wondering whether HP's long term goal is not so much the ReRAM per se, but a derivation of the technology in the form of High Density Configurable Logic (HDCL)and a nicely fattened IP portfolio.
Should Xylinx and Altera be concerned?
As usual this will all take much longer than anyone at first anticipates as nothing is easy...,
I was going to write something interesting, but I forgot what it was. Flash has a lot of process steps and time-consuming test needs (retention bake, test patterns, etc.), so I'll be glad to see it replaced by something more economical. Writes will be much faster. In 10 years I might have ReRAM in my pocket, on my 1TB thumb drive.
As memristor is fourth basic electric element, it will have many potential new different applications. What these other applications will be? Will it be able to help make progress in solving problems related to Alzheimer and Parkinsonís diseases?
