Every time the MFT cannot be extended due to some file being in the way, the MFT will gain a fragment. Also from what I understand is that RAM defraggers simply just reallocate all possible RAM to themselves and then deallocate it properly as all programs should. Memory that's locked by the application (see mlock() and mlockall()) can't be moved: by locking the memory, the application is indicating that moving the memory isn't acceptable.
