Samsung finishes the development of the world’s first DDR4 DRAM

Although DDR4 DRAM is not expected to be in anyone’s computer system until the beginning of 2012, Samsung is already done developing it. The new DDR4 modules will not only be faster than their DDR3 predecessor, but they are going to run using less power as well.

In order to accomplish the lower power consumption of the modules, Samsung is using the 30nm-class process technology.

Now you may be wondering how much faster the new DRAM is compared to the current DDR3. We can’t know for sure, until the production of actual units starts, but here are some initial figures for you. The speed of data transfers that DDR4 DRAM can achieve is 2.133Gbps (gigabits per second) at 1.2V, compared to the DDR3 DRAM, which can only pump out 1.6Gbps at either 1.35V or 1.5V.
The modules make use of a new circuit architecture, which helps them make the jump from 1.6Gbps all the way up to 3.2Gbps. This is tremendous improvement compared to the usual speeds of 1.6Gbps and 800Mbps for DDR3 and DDR2 DRAM respectively. In addition, when used in notebooks, the new DDR4 DRAM is expected to be 40% more energy efficient than the commonly used 1.5V DDR3 modules.

Samsung-made Google Nexus S is now official, 10 days to launch

As expected the Google Gingerbread announcement was garnished with a new Google handset, dubbed Nexus S. The Samsung-made smartphone features the latest Android version and an unusual curved display that should be more comfortable to handle and hold next to the face.
Quite expectedly the Google Nexus S features almost the same specs as the Samsung's best-selling Galaxy S. The 4-inch WVGA Super AMOLED screen returns, embedded within a curved glass and protected with anti-fingerprint coating.
Nexus S is powered by the 1GHz Hummingbird processor, packs 512MB RAM and 16GB internal memory, but there is no word about microSD slot. There camera department stays the same as on the Galaxy S - a 5 megapixel snapper with HD camcorder - but this time it comes with a LED flash. There is a secondary video-call camera too, but no FM radio.

Google Nexus S
Finally the connectivity is top-notch as usual - Wi-Fi b/g/n with DLNA support, GPS, quad-band GSM and tri-band 3G with HSPA, Bluetooth and even Near Field Communications capabilities.
Google Nexus S runs on the latest Android v2.3 Gingerbread and offers all Google goodies.



The Nexus S will hit the US via T-Mobile and Best Buy on 16 December, while the European premiere will be on 20 December in UK at Carphone Warehouse

Samsung announces next-gen LCD screens, LG works on QLED

It appears that the display wars are not going to end anytime soon. Both Samsung and LG announced new generation display technologies, which as you can imagine, promise to be better than anything you may have seen so far.
First off it was Samsung's Mobile Display division that showcased a working prototype of the Super PLS LCD. It is said to offer 100% wider viewing angles and 10% higher brightness than conventional IPS LCD screens (as the one found on the iPhone 4 and iPad). Just don't get misled by the word "conventional" - the IPS LCD unit on the iPhone 4 is among the best we've seen.

Now we can imagine 10% brightness boost can be achieved, but doubling of the viewing angles seems a rather long shot - IPS LCD just cannot be improved that much in this aspect. After all, those are already unbelievably good.
The Super PLS displays will support resolution up to to WXGA resolution (1280 x 768 pixels) and should cost about 15 percent less to manufacture. Mass production starts early next year so we will hopefully get to see them in action pretty soon - perhaps some time around the MWC 2011 the upcoming February.
On the other side of the camp, LG doesn't have a working prototype to show just yet but it has announced that it has teamed up with QD Vision for the development of Quantum Dot LED (QLED) display units. Dubbed "ultimate solution for displays" QLED should give unmatched power efficiency, providing more brightness, while consuming less power than any currently available OLED technology. Can't wait to see those too.

QLED displays should also offer more accurate colors and be cheaper to manufacture. You can find out more about them at QD Vision's website. The bad news is that QLED technology is still in development and there's no saying when it might be mounted on an actual device
