ReRAM ??
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 -- | 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.

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.

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.

Next year. 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. It's an 'element' because it cannot be constructed from the other 'elements'. 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. Rick |

Anyone know the V-I behavior of these device? Thanks! ...Jim Thompson Lots of worthless PhD stuff out there. Weaned to engineering level, I found people addressing modeling... http://krex.k-state.edu/dspace/bitst...iKerur2010.pdf exciting stuff there, can't wait to see the meminductor and memcapacitor. I call shots on the memsuperconductor. http://www.electro-tech-online.com/c..._210_214-4.pdf http://www.roznovskastredni.cz/biole...es/eds10_1.pdf http://arxiv.org/abs/1002.3210 http://www.cnr.berkeley.edu/~goster/pdfs/Memristor.pdf ...Jim Thompson |

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? speaking of, can anybody clearly explain a memristor in about 3 sentences or less? 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 Google memristor Leon Chua 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. Chua's latest definition of memristor would include fuses, antifuses, and anything that burns out when you run current through it. anybody interested in my room temperature superconducting cold fusion memristor technology? Only if it includes a global warming component, and some stem cells. It has that too, it uses fuzzy logic.

The antidiagonal entries on the plot of four quantities store energy, while the upper-left, at least, dissipates power. Perhaps the entire main diagonal dissipates. - Resistance is the ratio of voltage to current; the product is power (real dissipation, nonconservative). - Capacitance is the ratio of charge to voltage; the product is energy (stored, conservative). - Inductance is the ratio of flux to current; the product is energy (stored, conservative). - Memristance is the ratio of charge to flux (or the inverse, whichever); the product is technically energy * time, or momentum * length.

Instead of *dissipating* power as voltage and current (resistor), it *stores* power in the form of flux and charge, either by chemical reaction or by rotational inertia. Paul The units for a memristor is said to be Ohms. It dissipates just like a resistor. This has been used to argue it's not a new fundamental device since, it is claimed, a new fundamental device would require a new unit of measure. I'm not saying that's 'true', just that it's an argument made. Note, however, that they're both a ratio of (in generalized terms) 'quantity vs potential' with the difference being one is the differential of the other. e.g. dq-idt. It might be better to call the memristor unit Rt, or OhmT, to accommodate the 'memory' function. Or, put another way, it strikes me that saying 'ohms' for a memristor is akin to noting the volt and current of an inductor or capacitor at a specific moment in time. It's valid for that moment but is different at others and the same goes for the memristor's 'Ohms'. It changes over time, depending on flux and charge, so Ohms is an insufficient measure of it's overall, time variant, characteristic. A battery is not a passive device and a motor is not fundamental as it can be modeled by fundamental devices. Someone mentioned the diagonal. Yes, the inductor-capacitor diagonal are energy storage elements. The resistor-memristor diagonal are dissipative elements. 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 ;-) ...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.
