Samsung's new low power DDR4 memory chip could mean 4GB of RAM on your next smartphone
Get ready for a smartphone carrying 4GB of RAM. On Monday in Korea, Samsung announced that it has developed the first 8 gigabit (Gb), low power double data rate 4 (LPDDR4) mobile DRAM. The chip was built using the 20nm process and offers 1GB on a single die. This means it has the largest density on a DRAM component. In addition, Samsung says it provides a high level of performance with low energy consumption. Four of the 8Gb chips would combine to offer a single 4GB LPDDR4 package would would mean 4GB of RAM for a smartphone, or other device.

The 8Gb LPDDR4 mobile DRAM would allow for faster applications, higher resolution displays, longer battery life, and more advanced features for your device. With the new Low Voltage Swing Terminated Logic (LVSTL) I/O interface, data will be transferred per pin at a rate of 3200Mbps. That is twice as fast as the 20nm process LPDDR3 DRAM that is currently mass produced. It also achieves 50%  higher performance than the fastest DDR3 memory chip and at 1.1 volts, uses only 40% of the energy.

The chip will be used for top-shelf devices, including smartphones, and will be ready for shipment in 2014.

Samsung’s mobile RAM journey has been quite amazing. Here are the types of mobile memories the company produced throughout the years:
  • 2009: 256MB (50 nanometer 1Gb MDDR, 400Mbps)
  • 2010: 512MB (40 nano 2Gb MDDR, 400Mbps)
  • 2011: 1GB/2GB (30 nano 4Gb LPDDR2, 1,066 Mbps)
  • August 2012: 2GB (30 nano 4Gb LPDDR3, 1,600 Mbps)
  • April 2013: 2GB (20 nano 4Gb LPDDR3, 2,133 Mbps)
  • July 2013: 3GB (20 nano 4Gb LPDDR3, 2,133 Mbps)
  • November 2013: 3GB (20 nanometer 6Gb LPDDR3, 2,133 Mbps)
  • H1 2014: 4GB (20 nano 8Gb LPDDR4, 3,200 Mbps)

Hope intensive 3D games run smooth after the 4GB ram. Note 3 can't run some intensive games even with 3GB ram?!

4 GB is insane, but it's better to have big memory

4gb is standard for 2014, for 2015 I expect 8gb as standard for high end mobile device.

Sure, but only if you want to see your phone say "895725 applications closed" whenever you clear memory in the RAM manager. That would also mean that more apps will find their way to stay alive in the background since the system still detects that there's memory left for tasks. Sorry, but I'll stick to 4GB for a few years first. You can focus on amazing batteries now, Sammy.

unlimited power source has been a dream since the beginning of time. we are not getting there any soon by a year. ram technology is not that limited,.our ram keep doubling each year. high ram with low voltage requirement will improve the quality and duration we get from our limited battery juice.

I think 512 ram should be phase out now !1gb ram will be perfect for entry level android phones

IOS fun boys will never understand. You think smoothness means everything in the mobile world? 1.Our phones recognize usb storage devices when connected to them( no matter how huge your pen drive is my note 3 can read from it) 2. Note 3 has usb 3.0 which copies large files at an amazing speed 3. It pushes full 1080p via hdmi to external devices 4. It can run unlimited apps via multiwindow or pen window at the same time 5. it records video in 4k So you see, this are just a few reasons why android or samsung phones always have insane specs. They just do more than your tiny iphone which can not live in peace without itunes. Aint you tired of relying on itunes all the time?

I agree with you, but most iphone users will not have a clue what you are talking about....could you dumb down your posts, going forward? Thanks.... Sincerely, The Phonearena Team

When samsung announced the 2gb ram actually is 1.75gb usable, but when it comes to 3gig, which is note 3, total was only 2.3gb, so what's next, 3 gig usable only

Note 3 has replace my desktop. Together with an epson l355. I could print with and scan to my smartphone. I hardly switch on my desktop these days. Good saving on electricity bill.

Damn, this whispers the Note 4 all over - about 30-40Gb/s memory bandwidth, over 300Gflops, with a battery endurance that will significantly improve even upon the current Note. Yet, I have no plans to upgrade my Note 3 in the next 2-3 years. It really is that good

Wow, nice! But we need a phone with good battery life!

This RAM is the most energy efficient to date. According to article, it uses only 40% of the energy of the current LPDDR3 in Samsung top gun phones

Great! Let's hope that this will make it to the S5.

no one has ever did improved their batteries cause its too complex even top scientist from all over the world are still having a hard time to find a breakthrough not even the guys in NASA

Actually Korean scientists have found a breakthrough by Carbonizing a graphite-soaked LMO (lithium manganese oxide) Which is like a super lithium-ion battery that can charge 120x faster than normal. It's only a matter of time that they will come in a smaller form factor

Imagine this: Samsung note 4 releases with 4gb of ddr4 ram and some super energy efficient version of an Intel core i series proccessor that's expected to release. Then with the help of even more pixie dust it can run multi window with windows and android apps

We need to start educating consumers that despite the headline grabbing 4GB of RAM feature, this will still just be another Android phone with Touchwiz like the last million that Samsung have produced. We need to educate consumers to start demanding better software on our phones, not more RAM. Let's see you produce something like iOS, Samsung, instead of taking a free ride from Google. Let's see you produce an OS and ecosystem that's tailored to your hardware so that it's fast, efficient and doesn't need 4GB of RAM headline features to sell. We are sick to death of Android already!

educate people? So you think iOS is waaaaay better? I don't think so... It doesn't matter how fast you think the iOS over the Android. Both Samsung and Android offers more features that i called "usefull", unlike the iOS which still attached to the iTunes to upload most content, doesn't allow you to add an external sd card so you need to spend an extra 100 for more storage. I'm no haters just saying different person have a different needs, for me i didn't see the benefit of Apple iOS and the new 64bit architecture, simply because it didn't offer much to begin with...

ios is perty, it's smooth but have you seen the display on the 5s, it blurs as if the refresh rate is 10hz, no where near as nice as a note 3 s4 or lg g2 display

iOS has grown more boring - too much white screen - my wife went to Samsung and is much happier now...she has the mini Galaxy 3....which is basically the same size as an
