ReRAM ??

Started by Jim Thompson November 15, 2012
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!

speaking of, can anybody clearly explain a memristor in about 3 sentences or less?

free from wikipedia, current in one direction, increase resistance, current in the other direction, decrease resistance no current, resistance stays the same -Lasse

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. -- My liberal friends think I'm a conservative kook. My conservative friends think I'm a liberal kook. Why am I not happy that they have found common ground?

So the resistance INCREASES and approaches some asymptotic limit? ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

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. Rick

Well, it does if the current is going ----> thata way. If it's going <----- thisa way it decreases. The sign matters.

so it truly is as meaningless as it sounds.
