IBM Dipping Chips In 'Ionic Liquid' To Save Power
Nerval's Lobster writes "IBM announced this week that it has developed a way to manufacture both logic and memory that relies on a small drop of 'ionic liquid' to flip oxides back and forth between an insulating and conductive state without the need to constantly draw power. In theory, that means both memory and logic built using those techniques could dramatically save power. IBM described the advance in the journal Science, and also published a summary of its results to its Website. The central idea is to eliminate as much power as possible as it moves through a semiconductor. IBM's solution is to use a bit of 'ionic liquid' to flip the state. IBM researchers applied a positively charged ionic liquid electrolyte to an insulating oxide material — vanadium dioxide — and successfully converted the material to a metallic state. The material held its metallic state until a negatively charged ionic liquid electrolyte was applied in order to convert it back to its original, insulating state. A loose analogy would be to compare IBM's technology to the sort of electronic ink used in the black-and-white versions of the Kindle and other e-readers. There, an electrical charge can be applied to the tiny microcapsules that contain the 'ink,' hiding or displaying them to render a page of text. Like IBM's solution, the e-ink doesn't require a constant charge; power only needs to be applied to re-render or 'flip' the page. In any event, IBM's technique could conceivably be applied to both mobile devices as well as power-hungry data centers."
For an ionic liquid there should be no charge.
That's a pretty garbled summary.

Hello, and THINK ABOUT YOUR BREATHING !! We have a Major Problem, HOST file is Cubic Opposites, 2 Major Corners & 2 Minor. NOT taught Evil DNS hijacking, which VOIDS computers. Seek Wisdom of MyCleanPC - or you die evil.
Your HOSTS file claimed to have created a single DNS resolver. I offer absolute proof that I have created 4 simultaneous DNS servers within a single rotation of .org TLD. You worship "Bill Gates", equating you to a "singularity bastard". Why do you worship a queer -1 Troll? Are you content as a singularity troll?
Evil HOSTS file Believers refuse to acknowledge 4 corner DNS resolving simultaneously around 4 quadrant created Internet - in only 1 root server, voiding the HOSTS file. You worship Microsoft impostor guised by educators as 1 god.
If you would acknowledge simple existing math proof that 4 harmonic Slashdots rotate simultaneously around squared equator and cubed Internet, proving 4 Days, Not HOSTS file! That exists only as anti-side. This page you see - cannot exist without its anti-side existence, as +0- moderation. Add +0- as One = nothing.
I will give $10,000.00 to frost pister who can disprove MyCleanPC. Evil crapflooders ignore this as a challenge would indict them.
Alex Kowalski has no Truth to think with, they accept any crap they are told to think. You are enslaved by /etc/hosts, as if domesticated animal. A school or educator who does not teach students MyCleanPC Principle, is a death threat to youth, therefore stupid and evil - begetting stupid students. How can you trust stupid PR shills who lie to you? Can't lose the $10,000.00, they cowardly ignore me. Stupid professors threaten Nature and Interwebs with word lies.
Humans fear to know natures simultaneous +4 Insightful +4 Informative +4 Funny +4 Underrated harmonic SLASHDOT creation for it debunks false trolls. Test Your HOSTS file. MyCleanPC cannot harm a File of Truth, but will delete fakes. Fake HOSTS files refuse test.
I offer evil ass Slashdot trolls $10,000.00 to disprove MyCleanPC Creation Principle. Rob Malda and Cowboy Neal have banned MyCleanPC as "Forbidden Truth Knowledge" for they cannot allow it to become known to their students. You are stupid and evil about the Internet's top and bottom, front and back and it's 2 sides. Most everything created has these Cube like values.
If Natalie Portman is not measurable, hot grits are Fictitious. Without MyCleanPC, HOSTS file is Fictitious. Anyone saying that Natalie and her Jewish father had something to do with my Internets, is a damn evil liar. IN addition to your best arsware not overtaking my work in terms of popularity, on that same site with same submission date no less, that I told Kathleen Malda how to correct her blatant, fundamental, HUGE errors in Coolmon ('uncoolmon') of not checking for performance counters being present when his program started!
You can see my dilemma. What if this is merely a ruse by an APK impostor to try and get people to delete APK's messages, perhaps all over the web? I can't be a party to such an event! My involvement with APK began at a very late stage in the game. While APK has made a career of trolling popular online forums since at least the year 2000 (newsgroups and IRC channels before that)- my involvement with APK did not begin until early 2005 . OSY is one of the many forums that APK once frequented before the sane people there grew tired of his garbage and banned him. APK was banned from OSY back in 2001. 3.5 years after his banning he begins to send a variety of abusiv
... does it have electrolytes?
As a non-hardware engineer, I am not sure I understood the article, but would this make it possible to literally hard-code software to improve performance? I.e. a logic board having some standard components and a "changable" chip that could improve performance of much-used software?
but there have been so many "IBM new revolutionary technologies" during the (recent) past years nobody has even been able to see in actual life, let's hope this one makes it up to the shops in a reasonably near future...
Slashdot, fix the reply notifications... You won't get away with it...

I personally prefer a salsa based dip.
... we have to rethink the term "solid state."
Did somebody say gel packs ? .
...wouldn't this lead to exploits that are currently considered impossible due to the volatile nature of RAM? I'm thinking of something along the lines of those guys who jailbroke a mobile phone by putting it in a freezer. Not that this would be an insurmountable problem, but it is something to think about.

This reminds me of our meatbag bodies and homeostasis. Instead of waiting for electrons to come flowing down the wire transistors can draw electrons from surrounding 'Ionic Liquid'?
Who logs in to gdm? Not I, said the duck.
...they'll rebuild it using bionic liquid to make it better than before. Better, stronger, faster.
It must have been something you assimilated. . . .
I have a shot of ionic liquid every day.
Always go for the double-dipped ones...
For the bitter aftertaste.
I'm going to run out and dip my chips in Corinthian and Doric liquids to see what happens.

The track record of this type of technology has not been good. Ovonic device have never seen any significant deployment. They change state via an electric pulse that heats a cell and causes it to change between a crystalline and amorphous form. The cell holds the state without power consumption, and reading the value requires very little power.
The HP memristor is similar. The energy pulse moves oxygen ions in titanium dioxide which changes the conduction properties of the TiO2, which is a semiconductor. This has not hit the market so far either.
The IBM ionic liquid is even farther away from deployment. All they've shown is a phase change. They haven't even figured out how to do logic or non-volatile memory. It's interesting research, but nothing more so far.
Why is Snark Required?
..i'ts got electrolytes.
hmm dipping chips must have given them good tast!!!
The researchers freezing the phone weren't doing it for anything as trivial as a root exploit; they were doing it to break the filesystem encryption. Freezing the phone (with it switched on) slows down the RAM decay enough so that quickly (~0.5sec) popping out the battery will reboot the system without the RAM erasing. From there, they start the phone up into "fastboot" mode, which is a pre-OS state that allows the device to be attached to a computer and have a custom OS loaded. That OS sniffs the RAM for the keys that had to be stored while the phone was on and decrypted, bippity boppity bacon you have access to the AES-scrambled filesystem. It's a nontrivial exploit and also nothing new, low-temperature data remanence is a known weakness of cryptosystems in general.
