SK Hynix has developed the industry’s first 20nm-class 4Gb GDDR3 DRAM which provides power efficiency and fast speed performance. The memory chips will likely be used to power notebooks with standalone graphics processing units.
SK Hynix's new GDDR3 works at 1.35V voltage, which is 30% less power consumption compared to the previous 30nm class 1.5V product. The product operates at 1.80GHz clock-speed and processes up to 3.6GB of data per second with a 16-bit I/O. SK Hynix also offers GDDR3 chips with 1.5V voltage and 2.0GHz clock-speed.
The DRAM maker positions its new GDDR3 memory chips as eco-friendly solutions well suited for the low power laptops. Since integrated graphics adapters start to prevail in mobile and low-cost personal computers, fewer machines use standalone graphics solutions and the market for low-power memory is shrinking, it is highly likely that desktop graphics cards will also utilize low-power GDDR3 memory.
SK Hynix plans to start mass production of GDDR3 memory with 1.35V voltage in the fourth quarter of this year.
