Default [Q] Internal memory swap?

Hi all,

I have an S3 with a broken charging port and I ordered a new one through the replacement program Verizon has. A quote from a 3rd party repair shop was $70+shipping and I don't have soldering skills (and a new one was just $99 anyways). My question is, can I dissect the new S3 and old S3 and just swap the internal memory? I've taken apart my S3 before for repair work so taking both apart doesn't bother me. I thought about just doing a whole motherboard swap but wouldn't the internal memory go with it too? If anyone has any insight on where the internal memory is located on the mother board or how to swap them, it'd be appreciated.
