Samsung has been very big on new green memory products for servers and other computer systems recently. Earlier this month Samsung was touting its new 30nm DDR3 DRAM modules as the greenest in the industry. Samsung is now announcing the industry's first volume production 40nm DDR3 4Gb modules.
The new DDR3 RAM modules are aimed at use in data centers, servers, and high-end notebooks. The RAM is focused on low-power, which equates to less power consumption in the data center and longer battery life in notebooks. Samsung reports that its new RAM will help OEMs meet or exceed Energy Star power consumption ratings.
Samsung plans to move almost 90% of its DDR DRAM production to the 40nm process. A server that uses a 40nm 2Gb DDR3 module right now consumes 55W of power whereas the same server using 40nm 4Gb DDR3 modules consumes 36W. The new modules will be offered in 1.5V and 1.35V varieties.
