Elpida Memory's New 1 Gigabit DDR2 SDRAMs Are Ideally Suited for Digital TV, Set Top Box and Notebook PC Applications

Business Wire, March 7, 2006

TOKYO -- 90 nm Process Improves Power Consumption and High-Volume Production Yield, x16 Configuration Improves Data Transfer Rate; Stacked FBGA Packages Enable High-Density Memory Modules

Elpida Memory, Inc. (Elpida), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced the availability of its second-generation 1 Gigabit DDR2 SDRAMs and six memory modules based on the new devices. The new devices are built using Elpida's state-of-the-art 90 nm process technology, and they complement Elpida's full line-up of DDR2 devices that are currently in high-volume production. The x16 devices provide a wider data path for digital consumer applications, and the FBGA packages enable thinner memory module designs. Dual In-line Memory Modules (DIMMs) based on the new devices include Registered and Fully-Buffered DIMMs (FB-DIMMs) for servers, as well as high-density Small Outline DIMMs (SO-DIMMs) for notebook PCs and Unbuffered DIMMs (UDIMMs) for desktop PCs.

"The expansion of our production based on 90 nm process technology enables Elpida to significantly improve the speed yield and packaging options of our high-volume DDR2 products," said Jun Kitano, director of technical marketing for Elpida Memory (USA) Inc. "With this new generation of DDR2, we now offer more device configurations, including x4, x8 and x16, as well as a full line-up of memory modules, including Registered DIMMs, FB-DIMMs, UDIMMs and SO-DIMMs."

Features and Benefits of 1 Gigabit DDR2 SDRAM:

The 1 Gigabit DDR2 SDRAM devices are available in four different data rate speeds: 800 Mega bits per second (Mbps), 667 Mbps, 533 Mbps or 400 Mbps. They are organized as either 32 M words x 4 bits x 8 banks, 16 M words x 8 bits x 8 banks, or as 8 M words x 16 bits x 8 banks. The high speed data transfer rate is achieved by its 4-bit prefetch, pipelined architecture. The supply voltage (VDD) is 1.8V /- 0.1V, and the operating temperature range (Tc) is 0-95 deg C. The devices are available in 68-ball or 92-ball FBGA packages for easy mounting on DIMMs.
