FB-DIMM Memory: the birth of serial RAM?

PCstats posted an introduction to FB-DIMM memory:

What was old is new again. Serial data links, once reserved for only the slowest exterior connections and least-demanding peripherals, have proven to be the future of computer design. Up until just recently though, one of the most essential parts of any computer has remained stubbornly parallel in its implementation; computer memory, or RAM as it also called. FB-DIMM memory (short for Fully-Buffered Dual Inline Memory Module) is a variant of standard DDR2 memory designed for server applications where both large amounts of memory and memory co-ordination and accuracy at high speeds are essential.
