Refer to the JEDEC Web site for available specifications. • • • • • FBDIMM Design Specification – pending JEDEC approval FBDIMM: Architecture and Protocol – JESD206 FBDIMM: Advanced Memory Buffer (AMB) – JESD82-20 Design for Test, Design for Validation (DFx) Specification Serial Presence-Detect (SPD) for Fully Buffered DIMM – JEDEC Standard No. 21-C, page 4.1.2.7-1 This DDR2 SDRAM module is a high-bandwidth, large-capacity channel solution that has a narrow host interface. FBDIMM devices use DDR2 SDRAM devices isolated from the channel behind an AMB on the FBDIMM. Memory device capacity remains high, and total memory capacity scales with DDR2 SDRAM bit density. As shown in the System Block Diagram, the FBDIMM channel provides a communication path from a host controller to an array of DDR2 SDRAM devices, with the DDR2 SDRAM devices buffered behind an AMB device. The physical isolation of the DDR2 SDRAM devices from the channel enhances the communication path and significantly increases the reliability and availability of the memory subsystem. Advanced Memory Buffer The AMB isolates the DDR2 SDRAM devices from the channel. This single-chip AMB component, located in the center of each FBDIMM, acts as a repeater and buffer for all signals and commands exchanged between the host controller and DDR2 SDRAM devices, including data input and output. The AMB communicates with the host controller and adjacent FBDIMMs on a system board using an industry-standard, high-speed, differential, 1.5V, point-to-point interface. The AMB also enables buffering of memory traffic to support large memory capacities. Refer to the JEDEC JESD82-20 specification for further information. PDF: 09005aef83de8266 htf9c128x72fz.pdf - Rev.
