48206-0001 Datasheet, PDF (1/3 Pages) Molex Electronics Ltd. – Fully Buffered DIMM Socket 240 CircuitWith Color Options

FEATURES AND SPECIFICATIONS
Molex offers the Fully Buffered DIMM with color options for server applications.
The development of Fully Buffered DIMM (FB DIMM) came from the need for larger
and faster memory capacity where memory coordination and accuracy at high speeds
are critical which DDR2 is not capable of supporting.
The FB DIMM is a variant of the DDR2. It combines the high-speed internal
architecture of DDR2 with a bi-directional point-to-point serial memory interface
which links each FB DIMM module together in a chain. The difference is here in which
the DDR2 uses a single memory bus.
Molex is an active member of the JEDEC work group that defines industry standards
for memory. This allows Molex to ensure that all our memory sockets are 100%
industry compatible.
