Elpida Ships 1GB DDR2 SDRAM

Elpida Memory, Inc (Elpida), Japan's leading global supplierof Dynamic Random Access Memory (DRAM), today announced the availability of its1 Gigabit DDR2 SDRAM device. Elpida's newest DDR2 devices were shipped tocustomers on 2 Gigabyte Registered modules* developed by Elpida so thatcustomers can quickly and easily evaluate the new devices on next-generationserver platforms. 4 Gigabyte Registered dual in-line memory modules (DIMMs) and2 Gigabyte SO-DIMMs based on the new 1 Gigabit device are currently underdevelopment and will be available soon.

"As a leader in DDR2 architecture and DRAM technology, Elpida now has thehighest data transfer rate combined with the industry's highest densitycomponent," said Jun Kitano, director of Technical Marketing for Elpida Memory(USA). "Elpida's module demonstrates the stability of the new 1 Gigabit DDR2SDRAM component. This component paves the way for faster development of 1Gigabit DDR2 SDRAM-based 2 Gigabyte unbuffered DIMMs for PCs, Small OutlineDIMMs for Notebooks, as well as 2 and 4 Gigabyte Registered DIMMs for serverapplications that need highest density, high-speed memory."

* Operation of the test modules was confirmed on Elpida's server system boardsprior to shipping. These modules were provided as a courtesy to customers solelyfor the purpose of testing Elpida's 1 Gigabit DDR2 devices.

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 128Million words x 8-bits (8 banks), respectively. The devices are produced atElpida's state-of-the-art 300mm fabrication facility in Hiroshima, and theyutilize Elpida's newly developed 0.10 micron process technology to create a68-ball FBGA package. The 1 Gigabit devices transfer data at up to 533 Megabitsper second (Mbps), and they implement world-class design technology such asadvanced circuitry. The devices also feature 1.8 V power supply with a CASlatency (CL) of 3, 4, 5 and a burst length of 4, 8. They also offer Off-ChipDriver (OCD) Impedance Adjustment and On-Die termination (ODT) for improvedsignal quality.

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