Micron Technology and Samsung Electronics, in cooperation with Intel, Altera Corporation, Open Silicon, and Xilinx among others have formed the “Hybrid Memory Cube Consortium” to develop and encourage adoption of a new storage interface specification. This new storage technology is based on Hybrid Memory Cube (HMC) technology, which is comprised of PCB, a thin logic layer, and stacks of DRAM chips. These memory chips are stacked vertically on top of one another and connected via TSV.

According to Tech Connect Magazine, Micron’s Vice President for DRAM Marketing is quoted in stating “HMC brings a new level of capability to memory that provides exponential performance and efficiency gains.” Hybrid Memory Cube technology is claimed to be capable of using 70% less power than current DDR3 memory modules (DIMMs) while being up to 15 times faster.
Reinforcing Micron’s position is Intel’s CTO Justin Rattner who talked very highly of the technology and it’s massive bandwidth and I/O improvements versus traditional DDR style memory designs. The Hybrid Memory Cube is capable of sustained transfer rates of 1 terabit per second, and is “the most energy efficient DRAM ever built” by a bits transferred per amount of energy consumed.
Both Intel and Micron have expressed that the HMC technology will be a boon for data centers and high performance computing that demands low power and high bandwidth memory storage. Assuming the numbers pan out, the Hybrid Memory Cube will be quite a leap in memory efficiency and will further accelerate adoption rates of so called “cloud” applications as well as more efficient high performance servers used in scientific research endeavors. All in all, the idea of the Hybrid Memory Cube is cool stuff, and it will be interesting to see if the actual memory will live up to its grandeur name.

There's a new type of Flash RAM looking to make its name on the street called FeTRAM, which sounds as interesting as the phase change memory that we've been hearing about. It is an improved version of Ferrous RAM, which is very fast and uses very low power but uses a destructive reading technique. The T in the new RAM stands for transistor, so instead of the charge on the memory cell being negated by a read, the transistor will hold onto the charge so that the data can be held long term. That spells the difference between a memory module good only for RAM and a module that can be used in an SSD. The Register points to an article citing a 99% reduction in power usage when compared to current flash memory technology.
"Nanotechnology boffins are exploring a new type of nonvolatile memory that not only has the potential of being faster than today's flash RAM, but also requires 99 per cent less energy.
Called ferroelectric transistor random access memory – FeTRAM, for short – the scheme is based on a new type of transistor that combines silicon nanowires with an organic ferroelectric polymer – P(VDF-TrFE) – that switches polarity when an electric field is applied to it."

G.Skill Breaks World Overclocking Record and Achieves Fastest Super Pi 32M Record For 1155 Intel Platform

G.Skill brought their “A game” to this year’s Computex 2011 show by shattering the current super Pi 32M record on the first day of the show. With the help of famous overclockers Shamino, Fredyama, and Young Pro, the team was able to achieve a time of 5min 33.172 seconds. Using the company’s DDR3 2400MHz CL8 4 (2x2GB) memory kit, the team achieved the record overclock using an Intel 2600K processor at 6.34Ghz and memory clocked at 2340MHz with a CAS Latency of 6-9-6-25 1T. This was all run on an Asus ROG maximum IV Extreme motherboard.
Considering that the memory still had some headroom before reaching even stock clocks, G.Skill is confident that they will break even their record, saying that “this is just the beginning, we aim to achieve more records before the close of Computex 2011.”
The super Pi 32M program is often used as both a benchmarking and stress test application as it heavily stresses both the CPU, memory controller, and RAM by calculating Pi out to 32 million digits. As a single threaded program, it is heavily dependent on CPU clock speed-which is why the G.Skill team focused on low RAM timings as well as getting the CPU clocks up as high as possible in order to grab the world record.
G.Skill Guarantees Compatibility of Dual Channel RipjawsX and Sniper Series DDR3 RAM Kits With Z68 Motherboards
G.Skill recently announced that it has finished testing its RipjawsX and Sniper series DDR3 memory kits on Intel’s latest Z68 motherboards. The RAM manufacturer stated that it has “worked closely with all the major motherboard manufacturers to ensure the best compatibility between all Z68 motherboards available in the market and G.Skill’s current memory product line.”
The testing in question included memory kits from 1333 MHz CL9 DIMMS to their highest clocked 2200 Mhz 16GB set using Hyper PI 0.98b and MemTest.
It’s nice to see that G.Skill is willing to support their current product lineup as new motherboard tech is released. You can read more about warranty and product information here.
Corsair, a popular PC component manufacturer founded in 1994, today announced the production of a new DDR3 memory kit for their Dominator lineup. The new 2x4GB memory kit is capable of running at 2400 Mhz at a voltage of 1.65V.
Corsair states that the 2400 Mhz kits are the result of a four stage testing process that fewer than one in every 20 memory chips pass. The Director of Memory Products at Corsair, Giovannie Sena stated that “The purpose of these kits is to help overclockers explore the limits of memory performance.” As the product of Corsair’s testing, they are eager to see what enthusiasts are able to get out of them.
Further, the new 8GB memory kit is capable of CAS latency of 9-11-10-30-1T. Each DIMM is fitted with Corsair’s DHX+ heat sink with removable fins, and the kit includes their AirFlow 2 GTL Cooling Fan to keep the DIMMS cool. Dubbed the Dominator GTX 8 GB 2400 MHz Kit, can be purchased today from Corsair for $499 USD.

If you didn't pick up one of the RAM kits that comes with an active cooler and are looking to not only monitor the temperature of your DIMMs but also get a light show going inside your case then Corsair has a treat for you. The $54 Corsair AirFlow Pro can do both and you can see it for yourself at Techgage.
"Have a desire to add a bit of 'bling' to your PC, but fear being ridiculed for it? Well, there's no better excuse for bling than with Corsair's AirFlow Pro add-on for the company's AirFlow 2 memory cooler. In addition to offering a hypnotizing light-show, the AirFlow Pro can also keep you informed on your memory's usage and temperatures."
