Elpida’s 70 nanometer technology means smaller, faster DRAM
Japanese memory chip manufacturer, Eplida Memory, is claiming a world first, with a recent announcement that it is using its new 70-nanometer process technology to manufacture 1-Gigabit and 512-Megabit DDR2 SDRAMs.
Smaller, faster DRAM from Elpida
The SDRAMs are being made at the company’s main fab facility, Hiroshima Elpida Memory Inc.
According to Elpida, it is currently realizing high yields from its 90nm process technology used in mass production, and same technology has been used to deveop the more advanced 70nm process technology.
1-Gigabit and 512-Megabit DDR2 SDRAM using 70nm process technology can be used in many applications, including high-end servers, high-performance mobile equipment, high definition digital TVs, next-generation DVD recorders, digital single-lens reflex cameras and other digital consumer equipment that must have advanced image processing capabilities.
The 70nm process technology enables 800MHz and 1GHz speed functionality in combination with high-performance operations, but it also means that chip size can be reduced, allowing incrementally more chips per DRAM wafer which increases productivity and volume overall.
According to Elipda, the technology has made possible the world’s smallest chip size for a 512-Megabit DDR2 SDRAM.
Production of DDR2 SDRAM using 70nm processing has already started, and the first product shipments are expected to begin in the first quarter of 2007.
Elpida plans to make aggressive use of its new 70nm process technology in the production of Mobile RAM(TM) for mobile phones and other mobile equipment and in memory products used in high-end digital consumer equipment and across the entire server/PC market.
