Samsung announces 8Gb LPDDR4 Mobile DRAM; will it show up in the Galaxy S5?

Samsung clearly want to put in more memory inside its future smartphones and tablets. Today, the company announced it has developed the first eight gigabit (Gb) low power double data rate 4 (LPDDR4) mobile DRAM that in theory could allow for companies to put in as much as 4GB of RAM in a smartphone.

Currently, most high end smartphones have 2GB of memory, although Samsung's own Galaxy Note 3 managed to put in 3GB of RAM inside its case. Today's press release states that Samsung's 8Gb LPDDR4 Mobile DRAM will allow for the creation of 1GB of RAM on a single die, fabricated by using a 20-nm process.

The press release states: "With four of the 8Gb chips, a single 4GB LPDDR4 package can provide the highest level of performance available today." It adds that the new memory chip will offer "50 percent higher performance than the fastest LPDDR3 or DDR3 memory" while also consuming 40 percent less energy.

Samsung says that mass production of the new memory chips will begin in 2014. It's more than possible that the company could include it inside their upcoming Galaxy S5 smartphone which is expected to launch sometime next year as well.

I'm waiting on the people to say "what are you gonna be doing to even use up all that RAM? Do we even need 8GB?"..

just keep bloating the OS and apps, of course.

It's just a numbers game continuing. Words fail me how I truly hate this consumer craze crap. I just hope it will crash and burn soon with the nanometer wall before any quantum or other solutions are found.

I am not sure what your problem is with this achievement. Samsung is now able to provide more memory in the same or smaller area while being 50% faster and 40% less energy. It's a total win for advancing mobile memory technology. In case you haven't notice, the DRAM is always active even when idling so saving 40% of energy is huge for battery life.

DRAM impact on the total power consumption is almost neglectable. The biggest power hog by far is the backlight of the displays, but that's a much harder target and with much less marketing capability.

They're really pushing the hardware on phones quick, few people need 3GB of RAM on their phones IMO and it probably only serves to allow for sloppy app development instead of better optimization.

I see people overlook the fact that the new memory is also 50% faster and far importantly 40% less energy. Having 4GB instead of 2GB is just a bonus. People complain that battery life is poor and Samsung comes out with better, faster, more efficient memory technology and suddenly 3GB+ is too much.

You're skipping over my point, sure the newer stuff is better when it comes to power and performance that however doesn't have anything to do with what I was talking about. When you see more and more apps suddenly need more RAM for no real reason because developers don't have the need to optimize as much.

They don't have the need to optimize on Android, because even the performance between phones are so fragmented.
As a developer, that's a reason to optimize. The high end devices will fly, and the low end devices will ideally still work.

I will say, having 4 GB of RAM in a phone is nice, but it's only nice for the rare app that actually takes advantage of that kind of memory. For the general case, the 40% energy savings will be lost by doubling the amount of RAM, thus hurting the battery life for a marketing gimmick until other phones catch up. I'd rather they give me 2 GB of highly efficient RAM that saves 40% battery life over a previous release than give me 4 GB of RAM that takes an extra 20% battery life (60% * 2 - 100%).

The real magic will happen when we start to see 8 GB of RAM in phones with reasonable battery life. At that point, full blown applications can run, and keep running in the background, that can be pushed to other screens (e.g., TV) similar to what Steam OS is doing, but probably more usefully given that everyone that owns a smartphone generally has it with them.

First of all, the 4GB in GS5 is pure speculation from Neowin. It's possible that Samsung will use their newest and best technology in their flagship phone. Maybe, maybe not. Maybe 2GB, 3GB, 4GB. Who knows? All speculations.

Second, this technology is NOT limited to just smartphones. What about laptops and tablets? What about x86 tablets with LPDDR4? Its performance is actually better than DDR4 now while also using much less power. http://www.semiconwest.org/sit..._Minho%20Kim_SK%20Hynix.pdf (Slide 7).

You can see the Intel Atom Bay Trail uses LPDDR3-1066, so imagine one single package of this new LPDDR4 is able to provide 4GB of memory at reduced power and increased performance. What's not to like? A lot of these mobile technologies are carrying to the less-mobile platforms.

I am not sure why there's such a dismissive attitude for this new technology. It has to start somewhere. At what point do you think we should move to 4GB of RAM on smartphones? Do we wait until there are software to demand it? Or do you provide the hardware so that you can actually have software to demand it? Why did Apple move to 64-bit and now suddenly everyone is rushing to push 64-bit ARM out?

Lazy developers who don't optimize their software don't get my money. It's simple as that. Vote with your wallet. Whether you give a lazy developer 1GB or 2GB, it's going to be subpar.

I'm talking in general terms and you're still being specific to this Samsung ram and the GS5. I never brought them up or disregarded the advantages of the new technology. All i said was that with this race on phones to add beefier hardware it's going to probably make for lazy development. The last thing we need to see is more and more apps on phone come with some form of hardware requirements like on the PC, IMO.

Not just on Samsung phones, Samsung's RAM packages are pretty much used on everything. Xbox, Playstation, Tablets, TV's, Embedded. You name it, they RAM it! To be perfectly honest, any company advancing technology is great because it benefits everyone, U highly doubt these chips are going to be exclusive Samsung hardware.

Samsung make great components, their actual products are ok and their software is horrible at least that's what I think. IMO their phones are quite over hyped for what they are.

Strange that everyone is writing that this is specifically about phones and more specifically speculating that it will be used for the next Android phone. (I could insert joke here about Android needing the RAM.)

However, Samsung makes RAM for a lot of devices beyond phones/tablets, and even with phones/tablets, they produce non-Android products as well.

Also, this product is more about efficiency, speed and physical size than just boosting capacity.

Technology advances immediately omg why does a phone need 4GB ram. Its not for phones its for everything like people have said and if android provides true multitasking then it will need it unlike WP and iOS's implementation which isnt true multitasking. Sure you dont specifically need it but business users may who want to switch between apps fast rather than having it have to resume from a suspended state every time they want do something else. either way samsung are doing good
