Elpida Memory announced that it has begun sample shipments of its new 32GB Load Reduced Dual In-Line Memory Modules (LRDIMM), the DRAM industry's highest density memory module. The LRDIMM consists of 72 advanced 40nm process 4Gb DDR3 SDRAM chips in a Double Density Package (DDP).

LRDIMM is a new standard for server memory modules that reduces I/O bus capacity by buffering the I/O bus line with the memory buffer (MB) to simultaneously enable higher system density and faster speed.

JEDEC, a standardization body for the semiconductor industry, is studying the adoption of LRDIMM standards. Elpida is actively engaged in promoting its own standard.

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 24 of its 32GB LRDIMM represents a next-generation 768GB capacity platform, or 1.5 times that of a system equipped with RDIMM.

Also, with a maximum a speed of 1600Mbps, which is 20% faster than the highest RDIMM speed of 1333Mbps, Elpida's LRDIMM is capable of meeting demand for higher densities and faster speeds in next-generation servers and data centers.
