Samsung begins volume production of 4Gb DDR3 DRAM chips at 40nm node

World's number 2 semiconductor chipmaker Samsung has announced it has begun mass-producing 4 Gb DDR3 devices using 40 nanometer (nm) class process technology. 40nm DDR3 DRAM IC chips consume 70 -80% less power than the DDR2 DRAM IC chips made at 60nm nodes.

"When our 40nm-class DDR3 was first introduced last July, we were well ahead of the curve for high density, high performance DDR3," said Dong-Soo Jun, executive vice president, memory marketing, Samsung Electronics. "Now, in just seven more months, we have introduced an ultra-low power 'Green Memory' - the 4Gb DDR3, which is double the density of its predecessor. At a module density of 16-gigabyte (GB), the 4Gb based module can save 35 percent in power consumption, to support customer requirements for more energy-efficient designs."

Samsung's 40nm-class Green DDR3 enables servers to comply with or exceed new Energy Star power consumption specifications.

Samsung says, production of the 4Gb DDR3 raises the amount of memory for use in servers to 32Gigabytes (GB) per module, which is twice the maximum density achieved with modules based on 2Gb components.

With the start of volume 4Gb DDR3 production, Samsung plans to migrate more than 90 percent of its DDR DRAM production to 40nm-class process technology.

Power consumption comparison between 60nm DDR2 and 40nm DDR3 as per Samsung: A module based on 60nm-class 1Gb DDR2 components consumes 210W, while a 40nm-class 2Gb DDR3-based module consumes 55W, an approximate 75 percent savings. However, the new 40nm-class 4Gb DDR3-based module consumes a mere 36W, which represents about 83 percent savings over the 60nm-class 1Gb DDR2 module. With growing concern about energy costs in data centers, these memory power savings translate into an overall reduction in server power of 10 percent per system.

The new 4Gb DDR3 supports both 1.5V and 1.35V specifications. Available memory modules include 16 and 32GB RDIMMs and 8GB SoDIMMs with a 1.6-Gigabit per second (Gbps) performance rate.
