14 DAY TRIAL // Samsung is one of the best-known semiconductor companies out there, having come up, over time, with plenty of innovations in the field of RAM memory, and that's also the case right now, the South-Korean giant announcing the development of an eight gigabyte (GB) registered dual inline memory module (RDIMM) based on its advanced Green DDR3 DRAM.
An 8GB RDIMM utilizing Samsung’s 3D TSV technology saves up to 40 percent of the power consumed by a conventional RDIMM, while the TSV technology allows for a dramatic improvement in memory chip density that is expected to offset the decrease of memory sockets in next generation server systems.
Furthermore, in the face of a 30 percent decrease in memory slots in next-generation servers, the TSV technology will be able to raise the DRAM density by more than 50 percent, making it highly attractive for high-density, high-performance server systems.
The TSV technology fabricates micron-sized holes through the silicon vertically, with a copper filling.
By using the ‘through silicon via’ bonding process instead of conventional wire bonding, signal lines are shortened significantly, enabling the multi-stacked chip to function at levels comparable to a single silicon chip.
Increasingly widespread adoption of the 3D TSV technology is expected to take place from 2012. Samsung plans to apply the higher performance and lower power features of its TSV technology to 30nm-class and finer process nodes.
Plus, Samsung revealed that the new memory module had been successfully tested by major Samsung customers and delivers superior performance, in particular because of its use of a three-dimensional (3D) chip stacking technology referred to as 'through silicon via' (TSV).
“At Samsung, we’re well positioned to accommodate early market demand for our state-of-the-art TSV technology as the industry continues to forge forward with even further advances in bonding technology to enable greater performance and operational efficiency,“ said Dr. Chang-Hyun Kim, senior vice president and Samsung fellow, memory product planning & application engineering at Samsung Electronics.
“Our 40nm-class RDIMM being announced today marks the introduction of a more advanced eco-friendly 'Green Memory' product line up utilizing 3D-TSV technology that is expected to enhance the leadership of Samsung and our allies in server and enterprise storage,” concluded Mr. Kim.
