Elpida Announces 1Gbit DDR2 SDRAMs

Elpida Memory 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 90nm process technology, and they complement Elpida's full line-up of DDR2 devices that are currently in high-volume production. DIMMs based on the new devices include Registered and Fully-Buffered DIMMs for servers, as well as high-density Small Outline DIMMs for notebook PCs and Unbuffered DIMMs for desktop PCs.

The 1 Gigabit DDR2 SDRAM devices are available in four different data rate speeds: 800Mbps, 667Mbps, 533Mbps or 400Mbps. They are organized as either 32M words x 4 bits x 8 banks, 16M words x 8 bits x 8 banks, or as 8M 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 to 95°C. The devices are available in 68-ball or 92-ball FBGA packages for easy mounting on DIMMs.

Elpida will offer six DIMMs based on the new 1 Gigabit devices:

• 4GB RDIMM for servers with data transfer rate options of 5.3, 4.2 or 3.2 Gbps (PC2-5300/4200/3200), and organized as 512 M words x 72 bits x 2 Ranks
• 2GB RDIMM for servers, with data transfer rate options of PC2-5300/4200/3200, and organized as 256 M words x 72 bits x 1 Rank
• 4GB Fully Buffered-DIMM for servers; with data transfer rate options of PC2-5300F/4200F, and organized as 512 M words x 72 bits x 2 Ranks
• 2GB SO-DIMM for notebook PCs, with data transfer rate options of PC2-5300/4200, and organized as 256 M words x 64 bits x 2 Ranks
• 2GB UDIMM (non-ECC); with data transfer rate options of PC2-6400/5300/4200, and organized as 256M words x 64 bits x 2 Ranks
• 2GB UDIMM (ECC); with data transfer rate options of PC2-6400/5300/4200, and organized as 256M words x 72 bits x 2 Ranks

Elpida's 1 Gigabit DDR2 x4/x8 devices based on 90nm process technology are available now in sample quantities. Registered DIMMs based on the new devices are also available now. 1 Gigabit DDR2 x16 devices, Fully-Buffered DIMMs, Small Outline DIMMs and Unbuffered DIMMs will be available in Q2 2006.
