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!

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?

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.

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.

I don't care about the label "element". I care about the idea that it
fills a gap in the general electronics theory as a "fourth element".
I've never found exactly what that is supposed to mean.

From considerable searching I conclude that the ReRAM is something
your door-to-door sweeper salesman might be hawking. Lots of claims.
Little do. Those who _were_ going to do non-volatile RAM with it are
"delaying" entry into the market for several years.
Even ran across a thesis and several papers where the "demonstrated"
Spice model had dangling nodes ;-)

From considerable searching I conclude that the ReRAM is something
your door-to-door sweeper salesman might be hawking. Lots of claims.
Little do. Those who _were_ going to do non-volatile RAM with it are
"delaying" entry into the market for several years.
Even ran across a thesis and several papers where the "demonstrated"
Spice model had dangling nodes ;-)
