Elpida Begins Sample Shipments of 32-Gigabyte LRDIMM, DRAM Industry's Highest Density

Elpida Memory, Inc., Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced it had begun sample shipments of its new 32-gigabyte Load Reduced Dual In-Line Memory Module (LRDIMM), the DRAM industry's highest density memory module. The LRDIMM consists of 72 advanced 40nm process 4-gigabit DDR3 SDRAMs 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 32-gigabyte LRDIMM represents a next-generation 768-gigabyte 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.

LRDIMM features:
  • At 32-gigabyte the industry's highest density memory module
  • A maximum operating speed of 1600 MHz (also supports 1333 MHz)
  • 1.35V/1.5V supply voltage
  • Compliant with JEDEC memory buffer (MB) and Raw Card K standards
  • Symmetric memory buffers maintain signal integrity
  • Elpida's original heat spreader to increase cooling and maintain reliable operation in response to the higher memory density
  • 40nm process 4-gigabit DDR3 SDRAM (DDP) installed
Elpida has already begun sample shipments of the new LRDIMM. Mass production is expected to begin in the first quarter of CY 2011.

We all know that no one needs more than 640k. :D

When they said that, they were thinking about personal computers. This is for servers.

It was nonsense, nonetheless. And they was Bill 'Almighty' Gates.

No one actually knows if he said it BTW. (source1)(source2)

But the point is it wasn't that unreasonable of a statement back in 1981.

My PC is just an interface to the cloud, so HA. :p

ACcckkk. My comment was tongue in cheek.
This is really very impressive memory tech.

Lol.. I think it was more like: "No one will ever need more than 640k" :)
