Elpida 2 GB DDR2 Registered DIMMs

Elpida Memory, Inc (Elpida) today announced volume productionof its 512 Megabit-based 2 Gigabyte DDR2 registered dual in-line memory modules(DIMMs). The 2 Gigabyte modules are the highest density available for the servermarket, and they offer high-speed performance with a data transfer rate of 4.3Gigabytes per second (PC2-4300). Elpida's newly developed stacked BGA (sBGA)technology creates a slim module (4.8 millimeter thickness) that increases airflow space between modules, thus improving thermal performance and reliabilityfor server applications.

"Elpida's 2 Gigabyte DDR2 DIMMs combine the industry's highest density moduleswith the maximum system performance available in the server market," said JunKitano, director of Technical Marketing at Elpida Memory (USA). "Our new sBGAstacking technology allows component testing to occur prior to stacking,resulting in improved module production and better yields. Elpida's ability toenhance production capability on high-density, high-performance modulesdemonstrates our readiness to meet customer demands for DDR2 DIMMs in volumequantities."

2 Gigabyte DDR2 DIMM Features
Elpida's new DIMMs (Part numbers: EBE21RD4ABHA-xx) are based on Elpida's 512Megabit DDR2 SDRAM devices that operate up to 533 Megabits per second (Mbps).The modules are organized as 256M words x 72-bits x 2 ranks, and they containthirty-six 0.11 micron, 512 Megabit DDR2 devices that are stacked and mounted onthe DIMMs using Elpida's unique sBGA stacking technology. The mounted deviceshave a CAS latency (CL) of 3, 4, 5 with a burst length of 4, 8. The standard240-pin DIMMs have a JEDEC-compliant outline with a slim thickness of 4.8 mm,and they support Error Checking and Correction (ECC) necessary for high-endserver applications. The modules also offer 1.8V operation - one-half the powerconsumption over DDR.

The 2 Gigabyte DDR2 registered DIMM is part of Elpida's comprehensive DDR2product portfolio that also includes 512 Megabyte and 1 Gigabyte densities.
