Samsung sees world first in DRAM chip

Samsung Electronics has developed DDR2 dynamic random access memory using 40-nanometer technology, claiming a world first among chip makers.

“With 40-nanometer technology, we can enhance production up to 60 percent compared with using 50-nanometer technology,” said Samsung in a release yesterday.

For chip makers, developing higher DRAM density means they can cut production costs and lead market trends by providing the latest DRAM chips at higher prices. Since chips are produced from a wafer, the smaller chips are, the more chips are produced out of one wafer.

A nanometer is one-billionth of a meter, and 40 nanometers is the equivalent of one-3000th of a hair.

Along with enhanced productivity, the 40-nanometer DRAM chip consumes up to 30 percent less electricity compared with its 50-nanometer counterpart. Currently, Samsung and the Korea-based world No. 2 Hynix produce chips with 50-nanometer technology.

Japan-based Elpida Memory will start to produce 50-nanometer DRAM chips within the first half of this year and U.S.-based Micron Technology still produces 60-nanometer chips.

The situation is worse for Taiwan-based chipmakers. Powerchip and ProMOS do not even produce 60-nanometer chips. Germany-based Qimonda went bankrupt last month due to tough market conditions.

This gives Samsung a head start on its rivals and industry officials say it will take two years for other chipmakers to catch up.

Meanwhile, industry experts say nobody knows when the world’s chip market will rally. “It’s hard to forecast when the market will rebound. When the financial crisis eases down, the market will see a turnaround,” said Brian Park, an analyst with Prudential Investment and Securities.

Samsung, the world’s No. 1 chip manufacturer, has been leading chip market standards by releasing the world firsts in DRAM products seven times over the past 10 years.

This 40-nanometer DDR2 DRAM comes two years and five months after Samsung developed a 50-nanometer DRAM in September 2006.
