2.3.2 DDR2 Memory Controller

All processors supported by the 3307800 CPU card have their own DDR2 memory
controller. The DDR2 controller has the following features:
Low-latency, high-bandwidth
667MHz 128-bit DDR2 SDRAM controller
Supports up to two un-buffered DDR2 SO-DIMM
Each SO-DIMM has a maximum capacity of 2GB
The DDR2 controller on the processor is interfaced to two SO-DIMM sockets on the
3307800.

2.3.3 Processor Electrical Interfaces

The supported processors have the following electrical interfaces:
HyperTransport™ technology: LVDS-like differential, unidirectional
DDR2 SDRAM: SSTL_1.8 per JEDEC specification
Clock, reset, and test signals also use DDR2
SDRAM-like electrical specifications.
