A few years ago, there were some programs for Win9x that "defragmented"
memory, but the real benefit of the programs were the fact that they
unloaded libraries from memory. (It was still cool anyway :-) )
I think it is a popular misconception because people think of memory in
terms of, say, a hard drive. There are penalties to accessing
fragmented data on a hard drive because of seek times related to the
physical movement of the read/write heads. There is no such physical
limitations to RAM. You can access random addresses in memory just as
fast as sequential addresses.
