SDRAM vs DDR-SDRAM

Hello,
I have recently bought a new motherboard(MB) that requires DDRam. I was wondering, if I buy that DDR-SDRAM, will it be compatible/usable with the new MB? Is DDR-SDRAM usable for both, SDRAM MB's and DRRam MB's?

Edit: Visit the link below for more refference.

DDR-SDRAM and DDRAM are the same thing; SDRAM is not compatible with DDR-SDRAM.
