Samsung's new RAM chips pave the way for smartphones with 6GB of RAM

Minutes ago, Samsung announced that it has started mass producing 12Gb LPDDR4 RAM chips using its 20nm process technology, being the first company on the globe to achieve the feat. As Samsung itself notes in its press release, this will allow the creation of smartphones with 6GB of RAM.

If these numbers don't seem to add up, then you should note the difference between lowercase and uppercase 'b'. Gb stands for Gigabit while GB stands for Gigabyte. As there are 8 bits in a byte, a 12Gb chip can actually hold in 1.5GB of information. By pairing together four such chips, Samsung can now make smartphones that come with a whopping 6GB of RAM.

According to Samsung, the new 12Gb LPDDR4 RAM chips will be 30 percent faster compared to the company's 8Gb chips while consuming 20 percent less power.

Back in December 2014, Samsung became the first company to mass produce 8Gb (1GB) LPDDR4 RAM chips. Smartphones such as the OnePlus 2, the Samsung Galaxy S6 edge+, and the Galaxy Note5 use four 8Gb chips from Samsung for a total of 4GB of RAM, which is the most we've seen on a smartphone so far.

Samsung says that future flagships will come with 6GB of RAM, which will allow for "seamless multitasking and maximum performance within the latest operating system (OS) environments". However, although more RAM is usually a good thing on any computing machine, it remains to be seen if 6GB of RAM isn't actually overkill on a smartphone, as it could appear at a first glance.

What do you guys think, is more RAM what high-end smartphones are currently missing?

Nice. Honestly my note 4 would run much more nicer if it was a lighter OS.. not all about how much ram.. it's about how the OS management. . Sure I'd love to have 6GB of ram lol.. I don't even use 16gb of ram on my macbook pro lol..

2/3 GB RAM is enough in a smartphone, 4 GB is overkill. I can't even mince words about what to say about how useless a 6GB module will be. The smartphone RAM segment requires faster and more efficient RAM, not more RAM.

Note 5 is having problems with multitasking even with 4gb ram. If you don't optimize your software,you have to beef up your hardware.

Samsung is using different kind of RAM management. No matter if you keep 16GB of RAM with touchwiz, it will shut down apps and won't keep more than 5 in memory. It won't matter even if you beef up the RAM to infinity. Note 5 will still have issues. The only way to fix that is software.

Note 5 can have more running apps than the s6 thanks to that extra gig of ram. You don't need to limit the no. if apps running in the background if you optimize the software or if you beef up the hardware.

*no. of

It does not after the latest update in s6. The number of applications in increased to 5 from 3 in s6 a few days ago via an OTA. It's not due to the extra gig of RAM the note 5 held (not anymore) more apps in RAM. it was the DRM settings of s6 that were set too low. 3gb RAM is more than enough to put more apps than note 5 does. It has nothing to do with software optimization. In fact, you can change those settings in s6 and note 5 by changing the DRM value in build.prop. It's just that Samsung intended it to be that way. It keeps half apps I memory so that it loads apps much faster, but doesn't freeze them like other android phones. You have noticed how quickly s6 and note 5 launch apps from cold compared to other android phones. That's because partially all apps are always in RAM and the system has to only load Hal of them.

Why would they set such a limit if the RAM was enough to have more running apps? Obviously because the ram is not enough for both the apps and touchwiz to run simultaneously all the time. If they put aside more RAM for opening apps quickly and that's preventing the device from having more apps running then it's definitely shortage of RAM isn't it?

59. TyrionLannister unregistered

That's not the case as devs on XDA have managed to run many many apps by changing these settings. Reasons why Samsung chose this kind of RAM management: 1. Apps load faster as they are partially in memory. 2. Battery savings as less apps are frozen. It's not shortage of RAM. It's definitely not that. 3 GB RAM is insanely high for storing a gargantuan amount of apps.

They chose that kind of RAM management because they felt that opening app a little bit faster was more important than multitasking? So if 3gb is enough and Samsung's RAM management doesn't allow you to have more apps running in the background, is the extra gig in the note 5 useless? I feel that they did it because they found it easier to make the apps open faster than to have more apps running in the background. Samsung devices are known for being resource hungry. I don't think anyone would choose to limit the number of running apps if you have enough RAM.

Actually Samsung made the S6, S6 edge, note 5 and S6 edge plus with ram aggressive management in order to keep the phone faster and smoother for at least 1 year due that Andriod will lag after couple of month of use.

Using the device doesn't make it slow. If your device is getting slow, it's because of the apps you downloaded or because you have updated to a newer version of the OS that isn't optimized for older devices.

This is exactly what you we need, it's a faster ram chip, and more efficient, and since it will only require half the materials needed to make the same capacity, it will also be cheaper(sooner or later). Just that "samsung developed a higher capacity, faster, and a more efficient single chip RAM" probably won't attract as much click.

Its only overkill if you phone doesnt do crap. 64Bit chips on ARM do the same thing 64Bit chips do one PC's. They load apps into memeory using double the space. The reason iOS is really crashing apps now is because apps that were forced to run 32Bit originally are trying to load in more memory space which they were nto designed for and they keep crashing. Just remember, if you run a 32Bit app on a 64bit CPU, its not going to load double in the RAM, but the CPU will still try to load it in a slightly higher amount of RAM space and it will likely crash. Also, more RAM means apps can have more capabilities because those extras can run from RAM and let the CPU do other things. Considering most apps can still only use one CPU core no matter how many the phone has, but opening more apps means you need more RAM. Without RAM the apps crash, stutter, and are very quirky, even on iOS. You can never have to much RAM. My laptop has 16GB of RAM and sometimes it feels it needs more. I've never had a computer outside a server with this much RAM. I lov eit because i turned off the Windows Swapfile and my laptop runs like a champ.

touchwiz needs more than 6gb ram to continue to run well after the first day haha

I'm thinking that much RAM could help expand the posibilities of what type of graphic intensive apps can be run in split screen mode on tablets. That much in a smartphone just seems like overkill.

You can never have too much RAM. Future technology is built on overkill. How can you possibly even pose that question and call yourself a technology author?

That may hold true when you are talking about devices that plug into functionally limitless power supplies. However, a device with a finite power supply, like a smartphone, has to pay the penalty in battery life for all RAM, not just unnecessary RAM.

50% higher capacity = 50% less chip per GB = less power needed to keep it running

meanwhile 2GB DDR3 is still standar memory size for laptop (that obviously more heavy multi-tasker compared to smartphone) :-/

I haven't seen a single laptop for sale with only 2GB of RAM, 4GB seems to be the standard today even for budget laptops. 6GB is becoming more and more the standard now too, despite Windows at most using 2GB of RAM.

My gaming laptop as 12 gb of ram never fully used it. No pagefile on my windows laptop too. Its so fast its crazy.

Of course the more the better, but if you give me a same model but $399 for a 4GB and $499 for a 6GB, I will take the $399 because 4GB is beyond enough, if $299 for a 2GB I even considerate if I'm normal users

in past few days i was just thinking abt this....phones with 6 GB ram. if alll goes well, note 6 may have 6 gb ram.

Apple showed us it is not just about more RAM, yes the more the better but optimization is play big role in any OS.

Please ask Apple why they offer Macbooks with 16GB of ram..?

Because OS-X is inefficient, insecure garbage, that's why.
