FBDIMM Sweet Spot—Managing the Challenges of Server Speed and Density
Our FBDIMM technology solves server challenges for you—and for your customers. Our high-speed, high-density FBDIMMs can give you virtually unlimited scalability of density and high-bandwidth solutions, all with an extremely reliable channel protocol.
How do we do it? At the core of FBDIMM architecture is an advanced memory buffer (AMB), which provides an interface from the DRAM through the high-speed information channel. Our FBDIMM technology uses DDR2 memory with a different topology, and this high-speed, point-to-point interface rapidly transmits signals among the controller, memory devices, and other modules, enabling simultaneous task performance (and eliminating additional dead time), while reducing soft errors.
With data rates as high as 4.8 Gb/s, our FBDIMMs enable extremely fast buffering—optimizing server performance, limiting data inaccuracies, avoiding crashes, and improving overall reliability. These modules are available in 512MB to 8GB configurations and can be scaled to meet almost any server challenge. We also offer low-voltage DDR2 Aspen Memory® FBDIMMs to save power in the data center.

The AMB maintains signal integrity and improves error detection methods, reducing soft errors. This simplified structure gives FBDIMMs a lower pin count and faster transmission rates than conventional architectures. Plus, they can perform reads and writes simultaneously, eliminating the read-to-read delay between data transfers. With speeds up to 4.8 Gb/s, our FBDIMMs enable fast buffering to optimize server performance.
Our FBDIMMs incorporate an enhanced cyclic redundancy check (CRC) that provides greater data and address/command protection than traditional server modules. You can also configure the CRC to suit your application.
