An interesting question came up on the LTspice List this morning concerning Spice modeling a ReRAM, a resistive element something like a Memristor, but "different" ;-)
The OP seemed over his head and couldn't quite vocalize how the ReRAM device behaves.
I tried surfing and ran into the hurdles that any real information is locked behind the IEEE fiasco.
All other links seemed more like Popular Science reviews than facts.
Anyone know the V-I behavior of these device?
Thanks! ...Jim Thompson

I love to cook with wine. Sometimes I even put it in the food.
speaking of, can anybody clearly explain a memristor in about 3 sentences or less?
1: It's really cool. 2: It's phenomenal. 3: It's revolutionary.
There -- isn't that easy?
OK, you're going to get all anal retentive and tell me that you didn't want the manager's overview. Fine. Here's my understanding of a memristor:
It is a device that acts like a resistor whose resistance is proportional to the integral of all of the current that has ever flowed through the it.
Oops. That's only one sentence. Sorry.

So the resistance INCREASES and approaches some asymptotic limit? ...Jim Thompson

If you can't get them, does it matter? I'll wait for the spec sheet.
What I want to know on the theory level, is how it is a "fourth" element of basic electronics that was predicted by theory? I've heard that claim, but it was never explained in any detail at all.

Well, it does if the current is going ----> thata way. If it's going
so it truly is as meaningless as it sounds.
doing that or reading any other story about them just makes them think I'm listening to some beggar with a sob story about how they need money to get a train ticket. None of it stacks up or makes any sense.
Next year.
It's an 'element' because it cannot be constructed from the other 'elements'.
You have very little imagination. It makes a very nice non volatile memory, to name but one use.
Chua's latest definition of memristor would include fuses, antifuses, and anything that burns out when you run current through it.

Yep. But the stated behavior is quite vague, and my surfing today indicates that planned roll-out in 2013 has been delayed to at least "mid-decade" whatever that means.
Sounds like a wet dream that turned out to be piss running down your leg... sort of like Chris Matthews' "thrill" >:-} ...Jim Thompson

Hmm, you make 'em sound potentially interesting. I bet they are horribly non-ideal.

It wasn't quite so vague originally but it looks like someone is trying to 'cover the planet' with generalizations. Patent games.
Bad analogy. His bed wetting won, again.
yeah, something that can barely be described and doesn't even exist is a great type of memory.
at least bubble memory exists.
It was easily described.
Whether it exists or not is irrelevant. The basic concept was described and you couldn't imagine a use for the concept.
HP has demonstrated real world devices using the basic principle and while there's debate over whether it's 'really' a 'memristor' the device works like one so the theoretical debate is largely moot. And entirely moot for your lack of imagination since, regardless of what it's 'called', it works and uses the concept you could find no use for.
anybody interested in my room temperature superconducting cold fusion memristor technology?
