This is a most excellent place for technology news and articles.
But memory compression works the same way swap works. When memory is needed LRU page is ~~written on disk~~ compressed, and where application needs to read data from compressed page it generates pagefault and OS loads(decompresses) page in memory. That's it.
It can be compressed in RAM, too.
Thanks, cap, this is what I said.
