Table 2–40 lists the DDR3 component reference and manufacturing information.
DDR2 SODIMM
There is a DDR2 200-pin SODIMM device, providing 1-Gbyte single-rank DIMM with
a 64-bit data bus. This memory interface is designed to run at a maximum fequency of
333 MHz for a maximum theoretical bandwidth of over 42.6 Gbps. The internal bus in
the FPGA is typically 2 or 4 times the width at full rate or half rate respectively. For
example, a 333 MHz 64-bit interface will become a 166.5 MHz 256-bit bus.
Table 2–41 lists the DDR2 SODIMM pin assignments, signal names, and its functions.
The signal names and types are relative to the Arria II device in terms of I/O setting
and direction.
