Elpida announced the volume production of its 512 Megabit based 2GB DDR2 registered memory modules. These are the highest density currently available for the server market, and have a speed of 4.3 Gigabytes per second (PC2-4300). Elpida developed a new stacked BGA (sBGA) technology, allowing to create slim modules (4.8 millimeter thickness).
2 Gigabyte DDR2 DIMM Features Elpida's new DIMMs (Part numbers: EBE21RD4ABHA-xx) are based on Elpida's 512 Megabit 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 contain thirty-six 0.11 micron, 512 Megabit DDR2 devices that are stacked and mounted on the DIMMs using Elpida's unique sBGA stacking technology. The mounted devices have a CAS latency (CL) of 3, 4, 5 with a burst length of 4, 8. The standard 240-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-end server applications. The modules also offer 1.8V operation - one-half the power consumption over DDR.

Elpida also has this type of memory in 512MB and 1GB densities.
