neural.disruption writes "According to the EETimes, HP is announcing that it 'plans to unveil RRAM prototype chips based on memristors with crossbar arrays in 2009.' I don't know if you remember the earlier story about HP Labs proving the existence of the Memristor that had been predicted in 1971 by Leon Chua, and has the nice property of maintaining a memory of the current that passes by it. This could bring us a new type of small non-volatile high-speed RAM at low cost because of the low complexity of the mechanism employed." Read more of this story at Slashdot. ...

This is a short blog update, introducing the ‘Memristor’, but let’s start with a history leason The story really starts back in the mid 1700’s, when scientists in Holand and Germany found that, if you applied a voltage using static electricity, the Leyden Jar could store charge. This was the first capacitor and the [...] ... Source: tranbonium.vox.com --- 45 days ago
Memristor HP announced in April 2008 that they had developed a switching Memristor . This is supposedly an electronic device that falls under the fourth , previously unknown and now debated, fundamental circuit element. In 1971 a link between charge and flux was missing from the four fundamental electromagnetic quantities (charge, voltage, current, and magnetic flux), and the element that linked them was named "Memristor", but was not developed. It is an interesting technology due to the fact that it could create non-volitile memory that is both cheap and many can fit in a tiny space. Part of the discovery is due to the new capabilities with regard to nano-technology. The uses are not fully known, but it might never see the light of day due to the domination of the transistor and other non-volatile memory that already exists. Basically a Memristor is fundamental a charge-dependent resistance element. This means that the magnetic flux over the element is a function of the amount of charge that has passed through it, simply changes resistance as it is "(dis)charged". However, don't take my word for it, as I understand the subject, but have done no research.

1 May 2008—Anyone familiar with electronics knows the trinity of fundamental components: the resistor, the capacitor, and the inductor. In 1971, a University of California, Berkeley, engineer predicted that there should be a fourth element: a memory resistor, or Memristor. But no one knew how to build one. Now, 37 years later, electronics have finally gotten small enough to reveal the secrets of that fourth element. The Memristor, Hewlett-Packard researchers revealed today in the journal Nature, had been hiding in plain sight all along—within the electrical characteristics of certain nanoscale devices. They think the new element could pave the way for applications both near- and far-term, from nonvolatile RAM to realistic neural networks. By Sally Adee, IEEE's Spectrum Issue May 2008 ...

Filed under: news An article in EETimes suggests that we may see a Memristor-based memory prototype in development as soon as 2009. The Memristor is claimed by many to be the theorized fourth passive circuit element, linking the fundamental circuit variables of charge and flux. This news may not sound that exciting to most computer geeks, but this new component could usher in a new era of computer memory by forming the basis of RRAM (resistive random-access memory). Scientists at HP labs have finally confirmed that the Memristor behaves as their theories predicted. The reason that the component will work so well for memory is that the process is nonvolatile and the bits themselves will only change after the CPU tells them to. The bits in current DRAM systems slowly fade out and require a refreshment every 50 nanoseconds. [via /. ] Read | Permalink | Email this | Linking Blogs | Comments ...
HP Labs has wrestled the Memristor into submission. Or, to put it less hyperbolically, by engineering control over the Memristor, they've made it possible to design integrated circuits that incorporate the devices. EETimes reported earlier this week that memristors, the fourth element of circuit design theory , will likely be the basis for HP's 2009 RRAM (resistive random-access memory) prototype chips. RRAM, a new kind of non-volatile memory that could be faster than flash, is also being pursued at other goliaths like Sharp, Samsung, and Fujitsu. But HP's plans go way beyond low-power chip design. Analog memristors, the researchers speculate , are a promising route to chips that operate more like the human brain than like a computer. "RRAMs are our near term goal, but our second target for memristors, in the long term, is to transform computing by building adaptive control circuits that learn," said [HP Labs principal investigator for memristors Duncan] Stewart. "Analog circuits using electronic synapses will require at least five more years of research." The same picture you will see in every article about memristors for the foreseeable future.

As words go, it's not the best crafted. Ungainly and unimaginative, 'Memristor' belly-flops rather than rolls off the tongue. It is, however, usefully descriptive: anyone can see that the inelegant portmanteau has something to do with 'memory' and 'resistance' from the off. Like the three passive elements of an electrical circuit - resistance, capacitance and inductance - it's a measure of certain electrical properties of a component. It wasn't brought up in GCSE science, though, because no-one has ever seen or built a Memristor before now. Breakthrough A material with memrisistance - even clumsier as an abstract noun - acts like a traditional resistor, throttling current flow in an electrical circuit. It's hugely significant for the computing world, because a memresitor retains all information about its state after it's been powered down. Unlike other forms of non-volatile memory, such as fl ash or magnetic media, a computer memory format based on Memristor technology would be fast enough to use as system RAM. A Memristor is also much simpler and smaller than a transistor - all its properties are in one wire. Because it can have variable resistance, rather than just an on/off state, it also has profound implications for analogue computing and applications like neural simulation. Essentially, the Memristor opens the doors to instant booting machines, with superfast RAM access and very low power requirements. Even better, says the ...
