Samsung ships samples of Worlds highest-density memory module for server systems
Samsung announced today that it has begun shipping samples of the industry’s highest-density memory module for server systems. The 32 gigabyte (GB) module has been designed for use in advanced servers, which require high-density and high-performance features at low-power consumption levels. The highly-efficient Samsung 32GB RDIMM consists of 36 dual-die 40nm-class 4Gb DDR3 chips that can perform at equal or greater levels to a 40nm-based 16GB RDIMM with no increase in power consumption. In addition, replacing 12 DRAM modules of 16GB density with just six 32GB modules would achieve a 192GB total density, while allowing the DRAM operating speed in a two-way server system to rise by 33 percent from 800 megabit per second (Mbps) to 1,066Mbps, as power is cut by 40 percent.
Samsung is using the industries highest-density monolithic DDR3 device – a 40-nanometer (nm) class, four gigabit (Gb) DDR3 chip – as the building block for the new 32GB module. By equipping a dual CPU, two-way server with 32GB modules, a server system can have up to 384GB of memory. This allows for doubling the previously largest density of 192GBs per server with a power increase of less than five percent over that needed for a 16GB module-based system. Mass production of the Samsung 32GB RDIMM is slated to begin next month.
