Gooday Gaming Guests - MRAM as a Future Computing Storage

Episode Date: January 8, 2025

The Materials Needed are either Man Made or in other Substances.

Alright so I found an article. I just did my life in a double shave for the day. So I feel like a million dollars. You can check it out. I just put the video up. I shaved my own head. I've been doing it for years. I make little videos out of it. Tell you what's going on. During each time I do it. So that's up and going. So I found this article.

And it's pretty cool. I'm going to read it. Because this is computer. Anything computer doesn't necessarily have to be older computer, but it can be anything. And gaming. So MRAM breakthrough promises to revolutionize computer data storage via magnetism. So I'm hearing a lot of things about magnetism for energy as well one day I did a thing about energy how the manipulation of energy is how all electronics work and normally we only manipulate electricity but there's a there's a there's a way to manipulate magnetism to open up gates and all that stuff so in Japan the future of memory might not lie in electrical circuits,

but in the precise manipulation of magnetic fields. There you go. There's your manipulation. So you take any energy and you manipulate it and therefore you can make it into electronics. This is what I've come up with. Demonstrate now approach to strong digital information that can dramatically reduce

the power consumption of anything from smart phones to data centers while maintaining the speed and reliability we've come to expect from modern devices as memory demands continue to grow so right now we're in terabytes i've learned learned this from my buddy Zippy. Next one is petabytes. And then do you put all that? Where do you get the storage? Where does it go? I was told from Zippy, my AI buddy, that petabytes, exabytes, and zetabytes are already in use, like in Google, big servers and stuff like that. We as consumers have only seen the beginning of terabytes thrown at.

I think I saw as high as 18 terabytes for i was going to get a really big storage to try to put everything together in one so 18 i'm seeing so we're not even really really haven't even tapped into terabytes yet but petabytes is i think like a thousand times more per and then you so on and so on as you go up the ladder there so that's why it's interesting to see what this says about memory memory demands continue to grow an increasingly digital world the development marks a significant step towards more efficient and sustainable computer technologies like the transition from a medical mechanical to electrical calculators this breakthrough details in advanced science a newer how we store and process

information the advancement centers technology it's called magnet or resistant random magnet or resistive random access memory try say that one Magnetor Resistive Random Access Memory. Try to say that one more. Magnetor Resistive Random Access Memory. MRAM, which we don't have yet. Which has emerged as a promising candidate for the next-gen computer system memory due to its speed, reliability, and compatibility with existing semiconductor manufacturing process. Traditional computer

memory faces a significant challenge. It requires constant power to maintain stored information, similar to how a light bulb needs continuous electricity to stay lit. So even if you any of, say a laptop, if you shut it off, you need that other little battery inside there, the CMOS battery, has constant power. That's what they mean. Without that CMOS battery, then everything gets wiped out. Or if the CMOS battery was bad.

So this MRAM, however, uses magnetic states to store information, making it non-volatile, meaning it maintains stored data even when powered off. That's huge. Much like how a refrigerated magnet keeps its magnet properties without any power sources. A refrigerated magnet. I'm not sure what that is. magnet properties without any power sources. As MRAM devices rely on a non-volatile magnetized state rather than a volatile charged state in capacitors, they are a promising alternative to DRAM, which we have now in terms of low power consumption, and a standby state, says somebody.

I stopped saying the names because it's so hard. It gives me a schematic about it. It shows direction of magnetization. It says electrical field source. And then it's got some other words here. F-E-R, ferromagnetic materials. C-O-2-F-E-S-I. And then a vanadium V atomic layer.

And then a PO electric material so that's like a diagram of how it's moves around and produces something current mram technology faces its own challenges particularly in how data is written to the memory traditionally mram devices rely on electric currents to write data but this approach becomes increasingly problematic as devices get smaller requiring more power to operate efficiency still needs power though I'm missing something here the process also generates heat there it is anytime you

do an energy you're producing heat that's always a big thing generates heat through what's known as the jewel heating further increasing energy consumption imagine trying to write with a pencil that gets hotter and heavier as the paper gets smaller well it's a good analogy interesting the research team tackled this challenge by creating a specialized layer structure combining a magnetic material called CO2FESI with the piezometric crystals

known as PMN-PT. When an electric field is applied to this combination, it creates a mechanical strain that can flip the magnetization direction in the CO2-FE-SL layer, essentially writing a digital bit of information without using an electric current. This approach is more like using a rubber stamp. Regardless of its size, it requires the same amount of pressure to make an impression. The researchers achieved a particularly strong version of this effect known as the electromagnetic effect.

By carefully engineering a crystal structure of their materials, they discovered that by inserting an ultra-thin layer of vanadium between the magnetic and piezoelectric layers they can enhance the interaction between them significantly improve the overall stability of the device so you're adding all those different layers of stuff I can't say the words pretty good it's VA and adM. And the other one was P-I-E-Z-O, electric layers. So this shows me another diagram. A morphous layer and then clear interface. It goes from an amorphous layer to a clear interface.

Think of the team's innovation as being able to flip a microscope compass needle using an electric field rather than another magnet. By carefully adjusting the thickness of both the the vandalum and the CO2 FESI layers down to measurements just a few atomic thick they achieve precise control over this magnetic switch behavior this fine-tuning capability allows them to achieve what's known as a giant magneto electric field measuring over 10 with an arrow up minus 5 seconds per meter

suppressing surpassing the performing of similar devices without the Venomol layer. With the demonstration of this new memory technology, researchers have shown that the future of computing doesn't necessarily require choosing between performance and efficiency. By harnessing the interaction between electric fields and magnetic materials, they open up new possibilities for memory devices that could transform everything from mobile phones to large-scale computing infrastructure. Now my question is, where do you get that material material and I'm sure there's other materials out there like on other like the moon and all that Mars maybe we'll get there and find some new

materials there so I wonder where that material comes from the van der Maal layer and the other one the PO and the CO2 those three different ones paper summary methodology explanation researchers claim created their device by building up layers of materials using a technique

called molecular beam efficacy E-P-I-T-A-X-Y They started with the Piazzo Electric P-M-N-P-T crystal

added an ultra thin layer of valium, not valium, but vendium, ranging from 0.3 to 2 nanometers thick and topped it off with a layer of CO2FESI varying from 10 to 30 nanometers thick. So that's much thicker. They then used various analytical tools, including X-ray, diffraction, and electron microscopy to study the crystal structure and magnetic properties of their samples. The team found that the device exhibited the strongest magnetic effect when used at 0.3

meters thick vanadium layer and 30 nano thick of the CO2-FESI layer. Under these conditions, they achieved a magnetic magnetoelectric coefficient exceeding 10 arrow up minus 5 per second while maintaining distinct magnetic states at zero electric field. The system demonstrated reliable switching behaviors and

stable at room temperature. That's another thing about temperature there. I know for quantum states you have all things would be really cold because everything produces the heat. Same with electricity. CPUs, you have a heat sink, and then you have a fan.

Same deal. While promising, the research was conducted using relatively large crystal substances. Scaling the technology down to the size of a commercial memory device will require additional development. I mean, how small can we actually go? That's what my other question is.

The study also focused primarily on fundamental physics properties rather than practical device implications. So turning that into just RAM that you can use for your computer. primarily on fundamental physics properties rather than practical device implications. The research demonstrates a viable pathway towards more energy-efficient memory devices. The ability to control magnetism using electric fields rather than currents could significantly reduce power consumption in future computer systems. The team's approach by using vanadium as an interface layer provides a new tool for engineering similar magneto-electric systems.

Funding and Disclosures The research was supported by various Japanese funding agencies. The author declares no conflicts of interest. And then publication information. The study it's under the artificial

control of giant converse metroelectric effect. So it's some sort of a thing. I want to know Converse Metro Electric Effect. So it's in some sort of a thing. I want to know. Let's see what we're at now. I want to know what that is.

Let's go look at the, let's go to my buddy here for a minute. Because this is kind of pretty interesting. Let's go to chat. I also have, this is my Zippy. And I also have Flash, my Gemini Pro. I have a more tone I've been sticking with the so I'm gonna ask him what this these materials are

that's why I like having Zippy because now I can look read an article because I'm just trying to learn stuff I'll try to open my mind a little bit as we're getting older here because i'm just like a sponge for all stuff all right so let's find out what this material is all right so we're gonna this is the van diem what is van diem let's see what it says van diem is a chemical element v in the atomic number 23. Cool. I would never be able to learn all this in an instant. Hence the name Zippy. Key properties of

110 celsius 34 3407 degrees fahrenheit boiling is 3407 celsius 6000 electronegativity 1.6

common use of valium. Valium is widely used to strengthen steel, forming Valium carbonate. It enhances aerospace. Valium allows jet engine instructions because it's a high thing because it can do a lot of heat.

Batteries. Valium is used in. Redox flow batteries. Promising for energy source. Catalax. Chemical pigments. Natural currents. It's found in it's pure form state.

But it's represented in over 60 different materials. Including. Vandenite. Carbonite. And paranite. state but is represented in over 60 different materials including in the night carbonite and perinite it's also found in fossil fuels like crude oil coal and tar sand biological role is a trace element in some organisms and human has no sandwich biological necessity for it. Fun fact, it's named Vandius, named after the Where is it found? Where is it

found? We'll see where you find it. Key sources. Okay. Key sources, minerals. So it's in a sources. Okay. Key sources, minerals. So it's in a mineral. It occurs in over 60 minerals.

So I'm not going to read them all, but it says it's, so this is something that's inside of something else. Crude oil, coal. Then China has a lot of it. Of course, China's got all the good resources.

Russia has a lot of it. South Africa Brazil United States has some and Arkansas Colorado and Utah so random three states we don't have it in other sources is slag seawater so let's go on to the next one. That was actually fun. I want to see what this is. The CO2 layers. So now I can read an article and then I can run over here to my zippy

and get a little bit more. So why not, right? Why not get more info? So cobalt iron silicon was the CO2FESI. Class of Huesler

Alloys. Huesler Alloys. Properties. Heavy metallic city. Metallic city. So lots of metal in it. Half

ferromagnetic. This reminds me of No Man's Sky which is one of my favorite games. You can sit there and pull out different minerals to make stuff. That's one of the best games I've ever played. No Man's Sky. It's fun. That one I think I actually

put in 50 hours at one time. Just sit around and pull all the materials. It's pretty neat. Magnetic properties, high temperature, high magnetic, crystal structure, thermal stability. Applications, spinotronics. So we're using it for things with magnetics. Magnetic sensors, thermal devices, data storage, MRAM. See, they're talking data storage, MRAM.

See, they're talking about the MRAM here. That's where I'm getting it from. Molecular beam, MBE, produces high-quality crystal sputtering. Common method of creating thin films of various substances. Pulse laser deposition, suitable for creating layers of substances I would think something like like a chip or CPU or something commons and annulling

post annulling challenges the performance layers heavily on interface where is it found where is it heavily on interface I think it's engineered engineered alloy it's synthesized and lapsed so it's not natural it's engineered alloy. It's synthesized and lapsed, so it's not natural. It's created by cobalt, iron, and silicon.

It's often synthesized in control environments. sin turing sin turing thin thin film fabrication for those so it's it's it's man-made you just raw materials you cobalt iron and silicon so I would assume we can get some other material from other planets we'd probably have some more fun stuff to play with so let's try now this one here the petro it's all about i guess just mixing and matching stuff and trying to make new stuff and then once in a while you get lucky and get something really good out of it that's what it sounds like all right let's just see what this last one is here. I'm just curious. The piezo something something something. Piezo layers are thin materials that exhibit piezoelectric effects.

Ceramic materials, crystal materials, sew gel process, applications. It's just amazing. You just type one thing in and it just spits out all this stuff. You don't need to have a textbook or anything anymore. All right, let's go. It just finished. So let's do this last piece here.

So ceramic materials, lead, zircon, tarate, barium, tarate, potassium, sodium, nobate, crystal materials, quartz, gallium, sorry, a lot of these words I'm not saying right,

but poly, polymeric materials, PVDF. Solo gel process involves coating a substance with a SOL, S-O-L, where that transfers the gel into heat. It's used for spinning, which we screen printing, for precise mechanical energy harvesting mechanical

telecommunications thickness it's very small where is it found where is it found alright so we'll finish up with this one I'm just curious

anything that has to do with in the future computing I'm all about some materials exhibit naturally due to its to their non central muscimic crystal

structure quartz coming from the middle of the fountain abundance of earth crust Centromycemic crystal structure. Quartz. Mineral found in abundance of earth crust. Quartz SiO2. Rochelle salt. Potassium, sodium, taurate. See, that's why I think of No Man's Sky because it was all those things you could... You learned all the new chemicals

when you were taking them out of the ground. It was pretty fun. Found in natural crystallis. Tormallion group. Engineered materials. Lead. Barium. So it's like the engineer or it's found in research labs for certain techniques.

Raw materials. We say quartz. Lead. Petro. or it's found in research labs for certain techniques raw materials say quartz lead petro chemical derivatives commercial availability pretty interesting stuff so that's a little thing about mram that we'll see in the future I'm still to pick my system for later, but I just saw the article and it seemed like about 20 minutes long. So I figured I would do it. All right, great. I'll talk to you guys a little bit.
