Elpida 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 state-of-the-art 90 nm process technology, and they complement Elpida’s full line-up of DDR2 devices that are currently in high-volume production. The x16 devices provide a wider data path for digital consumer applications, and the FBGA packages enable thinner memory module designs. DIMMs based on the new devices include Registered and FB-DIMMs for servers, as well as high-density SO-DIMMs for notebook PCs and UDIMMs for desktop PCs.

Elpida Memory, Inc. (Elpida), Japan’s leading global supplier of Dynamic
Random Access Memory (DRAM), 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 state-of-the-art 90 nm process
technology, and they complement Elpida’s full line-up of DDR2 devices that are
currently in high-volume production. The x16 devices provide a wider data path
for digital consumer applications, and the FBGA packages enable thinner memory
module designs. Dual In-line Memory Modules (DIMMs) based on the new devices
include Registered and Fully-Buffered DIMMs (FB-DIMMs) for servers, as well as
high-density Small Outline DIMMs (SO-DIMMs) for notebook PCs and Unbuffered
DIMMs (UDIMMs) for desktop PCs.

"The expansion of our production based on 90 nm process technology enables
Elpida to significantly improve the speed yield and packaging options of our
high-volume DDR2 products," said Jun Kitano, director of technical marketing for
Elpida Memory (USA) Inc. "With this new generation of DDR2, we now offer more
device configurations, including x4, x8 and x16, as well as a full line-up of
memory modules, including Registered DIMMs, FB-DIMMs, UDIMMs and SO-DIMMs."

Features and Benefits of 1 Gigabit DDR2 SDRAM:
The 1 Gigabit DDR2 SDRAM devices are available in four different data rate
speeds: 800 Mega bits per second (Mbps), 667 Mbps, 533 Mbps or 400 Mbps. They
are organized as either 32 M words x 4 bits x 8 banks, 16 M words x 8 bits x 8
banks, or as 8 M 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’s new 1 Gigabit devices in stacked FBGA (sFBGA) packages enable
thinner module design which is critical for notebook PCs and blade servers that
require high-density memory. Elpida will offer six DIMMs based on the new 1
Gigabit devices:

  • 4 Gigabyte RDIMM for servers with data transfer rate options of 5.3, 4.2
    or 3.2 Gigabits per second (Gbps) (PC2-5300/4200/3200), and organized as 512 M
    words x 72 bits x 2 Ranks
  • 2 Gigabyte 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
  • 4 Gigabyte 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
  • 2 Gigabyte 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
  • 2 Gigabyte UDIMM (non-ECC); with data transfer rate options of
    PC2-6400/5300/4200, and organized as 256M words x 64 bits x 2 Ranks
  • 2 Gigabyte UDIMM (ECC); with data transfer rate options of
    PC2-6400/5300/4200, and organized as 256M words x 72 bits x 2 Ranks
