What Is Fully Buffered DIMM?

Fully Buffered DIMM (or FB-DIMM ) is a memory solution used to increase the stability, speed, and capacity density of a memory system. Traditionally, the data line on the memory controller must be connected to each DRAM module, so whether the memory widens the bandwidth of the access interface or speeds up the access interface, it will worsen the signal of the interface. Limiting the speed increase will also limit the memory space of the memory system, and FB-DIMM solves this problem in different ways. The JEDEC organization has formally finalized the release of FB-DIMM specifications.
