DDR2 SDRAM Memory Component
Three pieces of DDR2 SDRAM component (512Mb) is used on this board (Two Configurations).
The connection between FPGA and memories is shown like Figure.19.
Also Soft-touch connector that is produced by Agilent Technology is mounted between FPGA and
IC29 so it’s possible to confirm each signal using Agilent’s Logic Analyzer.
