Samsung Develops 30nm-class DDR4 Module
Samsung has developed the industry's first DDR4 DRAM module.
Tuesday Samsung Electronics said that it has successfully developed the industry's first DDR4 DRAM module using 30nm class process technology.
The new DDR4 module can achieve data transfer rates of 2.133 Gbps at 1.2V and also makes use of a new technology called Pseudo Open Drain (POD), which allows the module to consume just half the electric current of DDR3 when reading and writing data.
By comparison, 1.35V and 1.5V DDR3 DRAM manufactured at an equivalent 30nm-class process technology offers speeds up to 1.6 Gbps. Samsung added that--when applied to a notebook--the new DDR4 module reduces overall power consumption by 40-percent when compared to a 1.5V DDR3 module.
"By employing new circuit architecture, Samsung's DDR4 will be able to run from 1.6 up to 3.2 Gbps, compared to today's typical speeds of 1.6 Gbps for DDR3 and 800 Mbps for DDR2," Samsung said in a statement.
Samsung said that late last month it provided 1.2V 2 GB DDR4 unbuffered dual in-line memory modules (UDIMM) to a controller maker for testing. There are now plans to work closely with a number of server makers to insure the completion of JEDEC standardization of DDR4 technologies in the second half of 2011.
"The new DDR4 DRAM will build even greater confidence in our cutting-edge green memory, particularly when we introduce 4 Gb DDR4-based products using next generation process technology for mainstream application," said Dong Soo Jun, president, memory division, Samsung Electronics.

lol
damn you technology!
lol
damn you technology!
I hope I can pop in 6x 4GB DDR4 2400 into a X78 motherboard rocking a octocore Sandy.
I have to buy a new motherboard this year just for Bulldozer, now i have to buy another one next year as well because i won't be able to handle not having the best..
I second that. I might even wait for DDR5!
nah they aren't always able to take steady jumps. sometimes they milk a technology first with small speed incremental bumps. there's already ddr3-2100 but ddr3-2000 is more common.
33~66~100~133~166~200~266~333~400~533~667~800~1066~1200~1333~1600~2000~2100~2133->2333->2400->2666, ?DDR5? 2800->3000->3200->3466
just go by the 266,333,400 and add your next multiplier #
ram speeds are pretty predictable for every generation unless they start doubling DDR2 speeds at DDR4/5 Gen which i think more then likely since they're approaching the 22nm barrier by then with DDR5? i know i fouled something up some where but i'm too tired to think this late at night.
But yea, I still have my DDR2 1150 cards, and they do just fine. I'll have them another year or longer.
When new generations of DDR are released they typically start +25% to +33% above the clock speed of the last generation, with latencies that defeat the gain in performance. They're geared towards the notebook segment of the market - as that is the largest growing segment and has been for years.
As for GDDR4 and GDDR5 there are patent issues, ATI made some very intelligent moves in this part of the market a long time ago. Sadly their marketing department is too conservative compared to NVIDIA. They do have a double chipset support advantage though, since Intel isn't licensing tech to NVIDIA any more - NVIDIA thought they'd mention they want to try and make their own CPUs, and may side with ARM when Windows 8 is mainstream. This will just cost them a huge share of the high profit margin market segments.
Why not 8x4gb? or any capacity? Why not go Quad-Channel? You saw what performance enhancemnt the Nahnlem offered over dual-channel architecture.
Having a 256-bit memory bus seems logical, especially now that CPU manufacturers seem very keen on making on-die GPUs. A 256bit bus should increase the on board video performance significantly. If you are curios, just crack open you desktop or laptop with on-board GPU, and remove one of the memory modules:
AMD Radeon 4200 with 64 bit bus (1x2GB DDR2 667MHz) - 1670 3dmarks
AMD Radeon 4200 with 128 bit bus (2x2GB DDR2 667MHz) - 2118 3dmarks
AMD Radeon 4200 with 128 bit bus (2x2GB DDR2 800MHz) - 2271 3dmarks
AMD Radeon 5200 with 256 bit bus (4x1GB DDR3 1333MHz) - ???? (hopefully ~ 4500 3dmarks)
I used 3dmark 2006 and the laptop is a Compaq CQ61.
Additionally it would not be viable to use Unbuffered, Non-Registered, memory modules in a configuration beyond 6 DIMMs, let alone 4.
If people want such architectures they can pay for it by building a Xeon or Opteron Server/Workstation Hybrid. The motherboards will set you back at least $500.
Also, doubling the memory throughput in the x86 or x64 architecture does not double the performance, since a typical cache has ~ 80% hit rate, and there are several cache tiers in the hierarchy.
For those that want greater performance in 3D then they can use a PCIe 2.0 x16 slot, or multiple of them, and pay for a GPU with far more transistors, etc (It is the same with doubling the interface throughput of PCIe x16 slots, it is only a very small part of the solution, typically only used to load compressed textures into video memory).
You could cost it out, and it would be easily beaten by a modern, yet far more affordable, GPU created using the same fabrication tech (i.e. 32nm).
Or basically, going from very poor graphics performance to 'slightly less than very poor' graphics performance by tripling the cost of the motherboard and adding another 380 pins to the CPU, which will cause it's cost to skyrocket, isn't something that is going to appeal to consumers versus just adding in a daughter-board style video card at 1/10th the cost.
