Elpida develops 4-Gb DDR2 Mobile DRAM

Elpida Memory, Inc. has developed a 4-gigabit DDR2 Mobile DRAM made using 30nm process nodes. This new Mobile RAM features a low operating voltage of 1.2V, achieves a 1066Mbps high-speed data transfer rate, and uses roughly 30% less operating current compared with stacking two of Elpida's 40nm 2-gigabit products. Elpida says this product achieves the world's smallest class in chip size for a 4-gigabit LPDDR2 targeting mobile devices such as smart phones and tablet computers.

This DRAM is designed adressing the trend of increasing density of DRAMs and a strong demand for smaller, thinner, and lighter DRAM packages such as Package on Package (PoP) and Multi Chip Package (MCP). Elpida plans to ship the new DDR2 Mobile RAM as PoP, FBGA packages, and as a bare chip for MCPs.

Sample shipments of the new 4-gigabit DDR2 Mobile RAM will begin in April, and mass production is scheduled to start at Elpida's Hiroshima Plant in June of this year. Production is also planned at Rexchip Electronics Corporation in order to guarantee a stable product supply.
