HP Advances Next-Gen Memory Technology

samzenpus posted more than 3 years ago | from the newest-and-greatest dept.

HP 70

angry tapir writes "HP scientists have made a small breakthrough in the development of a next-generation memory technology called memristors, which some see as a potential replacement for today's widely used flash and DRAM technologies. In a paper to be published today in the journal Nanotechnology, scientists report that they have mapped out the basic chemistry and structure of what happens inside a memristor during its electrical operation."

what about F-RAM? (1)

kubitus (927806) | more than 3 years ago | (#36139024)

Ti introduced their new line of uControllers with F-RAM, saying it is 120 times faster than Flash.

-

except for real fast needs they have some k S-RAM.

as they are also using licensed technology like Fujitsu, we can expect more of this to come - maybe not yet for the PC!

Re:what about F-RAM? (5, Interesting)

vlm (69642) | more than 3 years ago | (#36139228)

The only real difference between FRAM and memristors, is FRAM has been licensing and shipping COTS product for over a decade, and memristors are a vaporware product from extremely deep pockets trying to bite a piece off that (admittedly very tiny) market by skating as close as possible to existing patents / copyrights / trademarks without actually being sued out of existence. Its kind of like asking what is the technical difference between a "turbo-" marketed product vs a "i-" marketed product.

Both are basically microscopic core memories. Magnetic field hysteresis, measure magnetic state by trying to force to a given state and seeing how much power it takes, none means its already that state and a bunch means it was the other state.

There are other theoretical uses for memristors. The killer is both devices are current mode devices, which means they'll almost certainly never be power-competitive with voltage mode devices. The other killer is they are not silicon, so that means scrap all the existing fabs and start over. Plus virtually everything out there is silicon based, so it'll be interesting seeing the hybrid devices. And the fourth killer is that memristor/fram technology is advancing, but mass produced silicon dram is also advancing, in fact for a decade or so has been advancing faster, making "modern core memory" ever less interesting.

On the other hand, depending on their temperature handling properties, a memristor based CPU that glows dull red with heat might be OK, don't know. I do know that off the shelf silicon for a variety of reasons doesn't "like" working above a couple hundred degrees, but memristors might not have the same limitations.

Re:what about F-RAM? (0)

NCR once made good magnetic core memory. Each bit 1/16 the size of a pinhead.
By having a tight program loop exactly resonate each bit, were able to make the core spin, then literally 'drop out' to the bit bucket. And there will be spin forces to 'test' a bit. Make it smaller, less 'glue' to stick it in place, or a thermal crack over time. You can miniaturize things, but I expect the same problems to pop up.
NCR , Burroughs and ICL (British) now Fujitsu should have patents or prior art sitting somewhere.

you have no way of knowing that at this point in time. it doesn't matter that it's a current operated device , it's power that counts.

if it takes 1nA @ 1V to enable/disable a memrister then a billion of them will cost you a watt. So what exactly would be the problem ? Based on my understanding of the physics I think it's completely possible that a memrister could be power consumption competitive with standard technologies.

However your point about the fact that it can't be fabricated using silicon-based technology is a good one, but the memrister seems to me to be simpler to fabricate than a FRAM cell, so that may end up being a wash.

Generally speaking I expect much of the PR today to be vaporware promoting, but the memrister is too new at this point. There might yet be something there.

Re:what about F-RAM? (1)

ChrisMaple (607946) | more than 3 years ago | (#36142670)

If by current mode you mean that it requires, like a tunnel diode, current to be running at all times to maintain a logic state, that is indeed a strong disincentive for many uses.

Are there any voltage mode devices anymore? Flash and DRAM are current mode, and my understanding is that even SRAM uses current mode sensing. I don't work in the FRAM group (I'm a flash guy), but TI's FRAM MCUs are supposed to be super low-power.

CMOS processes always have to be modified to support nonvolatile memory. Not sure what extra steps memristors would need but I doubt it would involve throwing out all existing equipment -- more like adding one or two things.

Your summary of HP's memristor devices is completely incorrect, almost maliciously so given your comments about trying to skate close to existing patents. They are not microscopic core memories. The mechanism is nanoscale ion mobility, not any kind of magnetic effect at all. As current flows through the device, ions move one direction, and its resistance changes. At some point there are no more ions to move, so it saturates. Reverse the current flow, the ions move the other direction, up till saturation.

IIRC, HP wasn't even intentionally looking for memresistance. They found odd unexpected hysteresis in the I-V curve of an experimental device built for another purpose. Someone on the team had read a paper about a fourth theoretical passive circuit element, the memresistor, and realized that's what was being observed.

Since the HP discovery, other labs have begun working on other possible approaches to building memresistors, including spintronic and magnetic devices, but that doesn't make the HP devices anything other than what they are: ion mobility devices.

There are other theoretical uses for memristors. The killer is both devices are current mode devices, which means they'll almost certainly never be power-competitive with voltage mode devices.

1. On what basis do you assert that current mode devices can't be low power? Or, equivalently, that voltage mode devices are inherently lower power than current mode devices? Don't you think it might be wise to actually investigate the particulars of any given device rather than make a blanket assumption?

2. HP seems to think their memresistor bit cell uses less power than flash. If they can achieve flash density (or better), with less power, and a better scalability story, they'll have something interesting, don't you think?

The other killer is they are not silicon, so that means scrap all the existing fabs and start over.

HP's memresistor devices are built from 2 layers of titanium dioxide. Why would it be impossible to deposit TiO2 on a silicon substrate? How is it any worse than F-RAM and other magnetic memory technologies, which also add unusual materials and process steps?

And the fourth killer is that memristor/fram technology is advancing, but mass produced silicon dram is also advancing, in fact for a decade or so has been advancing faster, making "modern core memory" ever less interesting.

So nobody should ever even so much as investigate alternative memory technologies?

Besides, who said it has to replace DRAM to be interesting? IIRC, DRAM was already the mature steamroller technology you depict when flash memory was invented. Despite being a thoroughly unappealing DRAM replacement, flash has matured into a steamroller tech of its own.

Why are you insisting that we should automatically pooh-pooh any attempt to research new technologies and develop them into practical products? Is it because of silly prejudiced attitudes like this?

On the other hand, depending on their temperature handling properties, a memristor based CPU that glows dull red with heat might be OK, don't know.

Yeah, because current devices are guaranteed to make things glow red hot, hur hur.

Re:what about F-RAM? (1)

thegarbz (1787294) | more than 3 years ago | (#36150380)

Except memristors aren't vapourware. [wikipedia.org] Memristors both theoretically exist, have been built in a usable form, and are continuously being improved to the point where they may become useful as the 4th fundamental passive electronic device.

By saying they are vapourware you're saying that everything was once vapourware which is a complete bastardisation of the term. Memristors like graphine and nanotubes are areas of research which are constantly expanding and developing and have both funding and a serious chance of making a difference in their respective markets.

Er no, a nanometer is a BILLIONTH of a meter, which would make it a 1,000,000,000/100th (a ten millionth) of a centimeter. The guy who wrote TFA somehow thinks a centimeter is a thousandth of a meter. Funny how cent comes from the latin centum meaning 1/100th (which is why there are 100 cents in a dollar, for example), and milli means thousandth, and still people who write "sciency" articles manage to screw them up.

Strange as it may seem it appears to have an odd quirk when put into practice in the UK...we have landed up with meters and millimetres as legal units but not centimetres. When I was studying for my "A" levels (many, many years ago) we were warned that use of centimetres might cause an adjudicator to drop us some marks in exams so it stuck in my mind rather well.

Not to mention how many hand-written recipes are in english. Who is going to go back through every note written by their relatives/friends/etc and convert it all to metric. To be effective, you would have to convert every oven/book/measuring-device/etc all at the same time.

No, we got $40 rebate coupons. Also, it wasn't everyone in the USA. At least according to the Wikipedia page, it "would only supply half the 73 million analog TVs not using a pay service", not everyone in the USA.

(I let mine lapse, twice, since there weren't any of the converter boxes around here for approximately the coupon price.)

Commonwealth English borrowed the -our spellings from French because France is across the channel from England. The United States, on the other hand, borders Mexico, which spells favorite "favorito" and color "color"; American English then analogized "behavior" from the other two because Spanish uses a different word ("comportamiento", meaning "comportment") for the concept.

DarkOx (621550) | more than 3 years ago | (#36140736)

You know what though. We have a huge investment in customary system tooling and you know what the metric system sucks every bit as hard, in the modern world. People who need to do lots of conversions between our customary units learn how and they learn good rules of thumb and math tricks to do so, its no big deal. Nobody does arithmetic by pen and paper any more; its either simple enough to do in your head or its reach for a calculator or computer; many people carry a phone all the time with these features anyway.

A base 10 system has just about as many problems for a computer as our customary units have. So there is no real value in converting. If anything we should create a base 2, system switch to that and then make everyone else follow.

Re:powers of ten (1)

partyguerrilla (1597357) | more than 3 years ago | (#36141052)

It isn't that I can't use metric. It is that I don't want to use metric. I am reasonably comfortable using metric with no (or just minimal) conversions to Imperial units. I know the two systems well enough, and I know which system I prefer.

The bit I've never gotten is why those who use metric assume that we don't because we are too stupid to do so. It really comes off as being needy and lacking in self confidence. Since there is someone who made a choice different than you, you collectively feel some need to insult and claim superiority. Ooh. Using metric makes a better person. Pathetic, really. Why do you care which system we use?

It probably has something to do with what system you "think" in. I use both metric and english, but when I look at something I estimate its dimensions in inches not centimeters, I feel in pounds not kilograms, and I gauge temperature on Fahrenheit. I know what 80 degrees F feels like but I have no clue what 30 degrees C feels like. The switch to metric will take a long time.

It's only one order of magnitude. "A centimeter" is something small that everyone can get their head around. "A millionth" is also something that's easy to take in. So he writes, "about a millionth of a centimeter", and he's right. To the general public, it doesn't matter if that's the correct size or if it's actually ten times smaller than that, "about a millionth of a centimeter" is just a way of saying "really, really, really small" in terms that everyone can grasp.

www.nantero.com for every request besides the pricepoint.

Let's compare to jcr's list...

Non-volatile: Check

Petabyte: They talk about a 10Gbit prototype chip. 10x10^9 bits 8x10^15 bits. Maybe density will improve if they survive till they make something real, but for now let's assume 10Gb. This is not exactly petabyte territory.

DRAM speed: Who knows, they aren't real specific.

$100, 1W, in a 1cm cube: Flatly impossible. They would have to improve bits per chip by about 5 orders of magnitude to meet any of these requirements. Probably a full 6 orders of magnitude (1PB on a single chip) to get it under one watt. (Driving signals between chips costs power, alas.)

(Implicit jcr requirement) Availability: Very, very unavailable. Guarantee you these guys have years (and several rounds of funding) to go before they can make anything suitable for purposes other than R&D. And there's no guarantee they've got something which will prove to be viable technology either.

You didn't actually look at jcr's requirements at all, now did you?

This is HP technology in which case, if it finally reaches the light of day, it will most likely: 1) suck 2) break within 2 years 3) lose information 4) be "supported", if that's the right word, by a bunch of illiterate indians and 5) suck.

BROTIP: Just because they speak a different language, or an accent different to your pure-inbred Iowan, it doesn't mean they're illiterate.

Memristors are most interesting not because of their ability to store data after power is removed, but for their ability to store any value between one and zero (on - no resistance, and off - no current). The non-volatile nature of the circuit will probably lead to early commercialization, but the really cool stuff will happen when people like Stanford's Professor Boahen get their hands on these things. The ability to store data in a non-discrete way will surely help to speed the development of processors that are very efficient by emulating biological methods of processing data. I have been following the development of memristors with great interest, and I would like to be the ten-millionth person to hail the imminent invention of our AI Overlords!

Isn't this just static ram(two capacitors entwined) miniaturized, and probably sustainable on a lithium battery? Haven't they considered that memristors is a fucking ridiculous name?

From what I understand, the memristor was theorized long ago and not by HP. The first use of the term was in 1960 by Bernard Widrow and the theory behind it was proposed by Leornard Chua in 1971. It is supposed to be the 4th fundamental basic circuit component with the resistor, capacitor, and inductor. To your point, the functionality of the memristor has been accomplished using the other three. The theoretical advantage of a memristor is that being a basic component, it should require less space and complexity to build in an IC.

Wake me up when it gets here TOMORROW, because. I have to do work TODAY with YESTERDAY's tech.
