Samsung has announced a new addition to its line of green memory products for computers. The company has started mass producing the first low-power 4Gb green RAM modules on 40nm process technology. The new RAM is designed to enhance energy efficiency ratings for servers that need to comply with or exceed Energy Star power consumption specifications.
The RAM is made in 4Gb modules for use in servers in capacities of up to 32GB per module. The capacity is more than twice that of the maximum that can be achieved with 2Gb modules. Samsung will migrate more than 90% of its DDR RAM production to the 40nm tech.
The smaller build process allows the RAM to be made more cheaply and sold at lower cost to OEMs. The new 40nm 4Gb RAM needs 36W of power compared to a 2Gb DDR RAM module that needs 55W of power.
