Description
This document describes the electrical and mechanical
features of a 240-pin,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. PC2-5300F, refers to the DIMM
naming convention indicating the DDR2 SDRAMs running at
333, MHz clock speed and offering 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.
The Advanced Memory Buffer also allows buffering of
memory traffic to support large memory capacities. All
memory control for the DRAM resides in the host, including
memory request initiation, timing, refresh, scrubbing, sparing,
configuration access, and power management. The
Advanced Memory Buffer interface is responsible for handling
channel and memory requests to and from the local DIMM
and for forwarding requests to other DIMMs on the memory
channel. Fully Buffered DIMM provides a high memory
bandwidth, large capacity channel solution that has a narrow
host interface. The maximum memory capacity is 288 DDR2
SDRAM devices per channel or 8 DIMMs.
