Lest anyone forget that Samsung dabbles in more areas than just displays , the technology guru has just begun sampling what it claims is the world's first 16GB double data rate-4 (DDR4), registered dual inline memory modules (RDIMMs), which at the outset are designed for use in enterprise class servers.Samsung said it's sampling both 8GB and 16GB DDR4 memory modules, which it produces using a 30nm-class process technology. These aren't the first DDR4 modules, however, as Samsung unveiled 2GB DDR4 memory sticks way back in December 2010."By launching these new high-density DDR4 modules, Samsung is embracing closer technical cooperation with key CPU and server companies for development of next-generation green IT systems," said Wanhoon Hong, executive vice president, memory sales & marketing, Samsung Electronics. "Samsung will also aggressively move to establish the premium memory market for advanced applications including enterprise server systems and maintain the competitive edge for Samsung Green Memory products, while working on providing 20 nanometer (nm) class based DDR4 DRAM in the future."According to Samsung, DDR4 technology offers the best performance out of all memory products currently available, and it's expected to reach twice the current 1,600Mbps throughput of DDR3 by next year. DDR4 modules also require just 1.2 volts, reducing power consumption by about 40 percent compared to DDR3 memory operating at 1.35V.As of right now, there doesn't exist a finalized JEDEC standard for DDR4, though Samsung is confident an official specification will be hammered out by August.
