Samsung announced today that it has just made the initial shipment of the world?s first and smallest high-density memory modules based on 2-gigabit (Gb), 50 nanometer (nm)-class DDR3.
Samsung is shipping 18 configurations of its high-density, DDR3-based modules, which are designed for servers. They include a 16-gigabyte (GB) registered inline memory module (RIMM) and an 8GB RDIMM (registered dual inline memory module). Last September, a 50nm-class 2Gb DDR3 was introduced for PC applications.
The 16GB high density module operates at 1066 Megabits per second (Mbps), which allows 192GB of total memory density for a 2-socket CPU server system. Samsung also is the first to offer 16GB RDIMMs operating at 1.35 volts, providing around 20 percent savings in power consumption over 1.5V DDR3 solutions.
In addition, the 16GB RDIMM features a dual-die package configuration, which is more efficient in cost and performance over the widely discussed quad-die configuration.
The 2Gb DDR3 consumes at least 40 percent less power than 1Gb configurations, supporting strong industry demand for lower power consumption, which is particularly important with server systems, as well as the new generation of notebooks.
According to market research firm IDC, the global DDR3 market is expected to reach 29 percent of the total DRAM market in 2009 and increase to 75 percent in 2011 (estimated in 1Gb equivalent units). Also, 2Gb DDR3 devices are forecast to take 3 percent of the total DDR3 market in 2009, with their share growing to 33 percent in 2011.
