240-Pin Fully-Buffered DDR2 SDRAM Modules DDR2 SDRAMThis document HYS72T64400HFA3S-B describes the electrical and mechanical
features of a 240-pin, PC2-4200F, PC2-5300F, ECC type,
Fully Buffered Double-Data-Rate Two Synchronous DRAM
Dual In-Line Memory Modules (DDR2 SDRAM FB-DIMMs).
Fully Buffered DIMMs use commodity DRAMs isolated from
the memory channel behind a Buffer on the DIMM. They are
intended for use as main memory when installed in systems
such as servers and workstations. PC2-4200F, PC2-5300F,
refers to the DIMM naming convention indicating the DDR2
SDRAMs running at 266, 333, MHz Clock speed and offering
4200, 5300, MB/s peak bandwidth. FB-DIMM features a
novel architecture including the Advanced Memory Buffer
This single chip component, located in the center of each
DIMM, acts as a repeater and Buffer for all signals and
commands which are exchanged between the host controller
and the DDR2 SDRAMs including data in- and output. The
AMB communicates with the host controller and / or the
adjacent DIMMs on a system board using an Industry
Standard High-Speed Differential Point-to-Point Link
Interface at 1.5 V By Qimonda
