Elpida Memory, Inc. (Elpida), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced the availability of its 1 Gigabit DDR2 SDRAM device. Elpida's newest DDR2 devices were shipped to customers on 2 Gigabyte Registered modules(a) developed by Elpida so that customers can quickly and easily evaluate the new devices on next-generation server platforms.
4 Gigabyte Registered dual in-line memory modules (DIMMs) and 2 Gigabyte SO-DIMMs based on the new 1 Gigabit device are currently under development and will be available soon.

"As a leader in DDR2 architecture and DRAM technology, Elpida now has the highest data transfer rate combined with the industry's highest density component," said Jun Kitano, director of Technical Marketing for Elpida Memory (USA). "Elpida's module demonstrates the stability of the new 1 Gigabit DDR2 SDRAM component. This component paves the way for faster development of 1 Gigabit DDR2 SDRAM-based 2 Gigabyte unbuffered DIMMs for PCs, Small Outline DIMMs for Notebooks, as well as 2 and 4 Gigabyte Registered DIMMs for server applications that need highest density, high-speed memory."

1 Gigabit DDR2 SDRAM Features

Elpida's 1 Gigabit DDR2 devices (Part numbers: EDE1104AASE, EDE1108AASE) are organized as 256 Million words x 4-bits (8 banks), and 128 Million words x 8-bits (8 banks), respectively. The devices are produced at Elpida's state-of-the-art 300mm fabrication facility in Hiroshima, and they utilize Elpida's newly developed 0.10 micron process technology to create a 68-ball FBGA package. The 1 Gigabit devices transfer data at up to 533 Megabits per second (Mbps), and they implement world-class design technology such as advanced circuitry. The devices also feature 1.8 V power supply with a CAS latency (CL) of 3, 4, 5 and a burst length of 4, 8. They also offer Off-Chip Driver (OCD) Impedance Adjustment and On-Die termination (ODT) for improved signal quality.

Elpida's 1 Gigabit DDR2 device also allows both DDR and DDR2 to be integrated on the same chip, making customer requests for conventional DDR SDRAM easy to achieve by switching between DDR and DDR2 via a metal option during the manufacturing cycle.
