DDR2 SDRAM, as the second generation dynamic random memory, is applied widely because of its large capacity, high speed and good compatibility. The poperties and working principles of DDR2 is introduced in the paper. Finally, the design of DDR2 controller is implemented on Cyclone IV FPGA by adopting DDR2 IP core, and it correction is verified by hardware test which compares read data with write data. The accuracy, better transplantablity and stability of DDR2 interface are validated in the design.
