Elpida Memory, a leading supplier of dynamic random access memory (DRAM), has announced it had begun sample shipments of its new 32GB load reduced dual in-line memory module (LRDIMM), the DRAM industry's highest density memory module. The LRDIMM consists of 72 40nm 4Gb DDR3 SDRAMs in a double density package (DDP).
Conventional registered DIMM (RDIMM) in a two-way server system only allows a maximum of 16 DIMM whereas LRDIMM allows up to 24 DIMM in the same system. According to Elpida, the use of 24GB of its 32GB LRDIMM represents a next-generation 768GB capacity platform, or 1.5 times that of a system equipped with RDIMM. The new LRDIMM operates at 1600MHz at 1.35V/1.5V voltage.
Elpida has already begun to sample shipments of the new LRDIMM. Mass production is expected to begin in the first quarter of calendar 2011.
Given the timeline of the release of Elpida's LRDIMM, it is more than likely that the new modules will be featured inside next-generation servers, including those with microprocessor that contain up to 16 cores.
