FBDIMM Sweet Spot—Managing the Challenges of Server Speed and Density
Data has to be transferred immediately, but it also has to be done accurately. Businesses want reliability on all levels—a panacea for data glitches, data inaccuracies, and system crashes. We believe we have that panacea. At Micron, we believe we run better and faster. And we believe 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. Yes, you read it right—an extremely reliable information path 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.

Micron’s Aspen Memory® Devices—Significant Power Savings
Looking for ways to lower power consumption in your servers while maintaining your performance and timing requirements? Micron's Aspen Memory® product line features the industry's first 1Gb-based, DDR2 reduced chip count (RCC) FBDIMM modules, specifically designed to lower data center server power consumption. Find out more about our efforts around developing energy-efficient products and how your application can benefit from our data sheets, technical notes, white paper, blog, and other resources.

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.
