Micron announced 256 Mb DDR2 SDRAM components
Micron Technology, Inc., announces the
industry’s first 256Mb DDR2 SDRAM components manufactured on 0.11µm process
technology. Intel has validated these components at DDR2-400 speed on the x4
and x8 configurations and DDR2-533 speed on the x8 configuration. In 2004, DDR2-400
will be used primarily in server platforms and DDR2-533 will be used in desktop
platforms.
The majority of DDR2 desktop computing architectures will use dual memory channels.
In a dual channel system, DIMM modules are installed and accessed in pairs.
Most 256Mb DDR2 components are currently used to build 256MB DDR2 PC2-3200/PC2-4300
modules, which are the preferred module density for 512MB dual channel platforms.
Building dual channel 512MB platforms with two 256MB PC2-4300 modules provides
twice the bandwidth of a single channel system using one 512MB PC2-4300 module.
In addition, 256Mb DDR2 components will be used to construct 128MB and 512MB
DDR2 modules to meet the price and performance requirements of a wide range
of system configurations.
