    it is. DDR2 667 is a 333MHz interface, which is supported in faster speed grade devices in stratix ii & iii.

    Whether you can use 4 interfaces would be dependent upon how wide each interface is... I believe you can get away with up to 4 - 36bit interfaces...

    2 cents,

    Thanks

    I understand that I can interface 4 DDR2 (width x16) with DLL interface type...

    Do you think like me?

    thanks

    I suggest you can use DDR2 SDRAM SODIMM, which is cheap and easy to control. For example:MT4HTF1664HY-667
