Samsung Electronics Co., the world\'s top memory chipmaker, said Friday it began mass producing the industry\'s most advanced double data rate-4 (DDR4) modules for enterprise servers. The 16 gigabyte and 32 gigabyte DDR4 dynamic random access memory (DRAM) modules, based on 20-nanometer class technology, will support the need for advanced DDR4 in rapidly expanding, large-scale data centers and other enterprise server applications, Samsung said. Enterprise servers are servers optimized for corporate use and have large data storage systems. The DDR4 DRAM using 20-nanometer class technology more than doubles the processing speed and consumes roughly 30 percent less energy compared with the existing DDR3 modules adopting the same technology, it said. The use of higher speed DRAM raises system-level performance and lowers overall power consumption significantly, Samsung said. \"The adoption of ultra-high-speed DDR4 in next-generation server systems this year will initiate a push toward advanced premium memory across the enterprise,\" Samsung said in a press release.
