Samsung has begun shipping samples of 40nm-class 32GB memory modules, the industry’s highest-density memory module for server systems. The 40nm-class, 32-Gigabyte memory module has been designed for use in advanced servers, which require high-density and high-performance features at low-power consumption levels.
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. This comes just one year after the company announced its 50nm-class 2Gb based, 16GB registered dual inline memory module (RDIMM) last March. The highly-efficient 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.
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.
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.
