South Korea's Hynix has developed the world's fastest and smallest one-gigabyte chip for mobile phones and other portable gadgets. The Icheon-based chipmaker said that the product is also the industry's first commercially available 1 GB mobile DRAM built on 66 nanometer process technology. The finer processing geometry reduces die size and improves the speed and power efficiency of the device. The new chip consumes very low power, under worst case conditions, extending battery life in a wide range of portable electronic devices. Mobile DRAMs are widely used in wireless and handheld applications such as mobile phones, digital still and video cameras, portable game players and navigation systems.

Hynix plans to begin mass production from the first quarter of 2008. The product will be also available as a package of DRAM and NAND flash, the firm said.
