The world's largest electrics company is pushing the envelope on memory technology, introducing changes that promise to give users more memory that uses less power.

Samsung said Monday that 30-nanometer DRAM have been qualified by customers and is ready to roll out. The new chips represent the most advanced DRAM chips yet from the company.

The use of tiny 30nm production technology puts Samsung ahead of rival DRAM makers.

The new chips will be in mass production in the second half of this year, and it plans to expand adoption of the technology to most production lines by the end of 2010.

Samsung had a bumper third quarter after the global industry of computer memory chips bottomed out while prices for dynamic random access memory chips rose.

But the new technology could prove to be a boon for the company.

Dynamic random access memory (DRAM) is needed in computers for multitasking and for large applications such as gaming or multimedia. They are also used in a variety of consumer electronics , such as phones, cameras, and tablet computers.

Samsung said its new chips consume 30 percent less power than chips made using 50nm production technology and can be made at more than double the cost-efficiency.

Analysts also expect the DD3 (3rd generation) category of memory -- the same as what Samsung is introducing -- to overtake DDR2 as the world's mainstream chip.
