So-DIMM vs. DIMM RAM

Hi,

I have a 13 inch black Macbook with a 2.2 Ghz Processor and the Intel Core 2 Duo. I want to upgrade my ram from 1 gb to 4 gb and I was wondering if there was a difference with So-Dimm and Dimm. This is the one I was interested in buying but the apple website sells SO-Dimm.

However it is a 200 pin Dimm

If someone could let me know if this would work or not that woul dbe great! Thank you
