... 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 buffer on the FBDIMM. Memory device capacity remains high, and total memory capacity scales with DDR2 SDRAM bit density ...
