I thought that most of them would steal some space in System RAM, re-route memory reads to that memory-range, and then mark that range as 'used'. If this is incorrect, how do they work?

On a low memory system, I think I can live with a few nanosecond delay at shutdown time in favour of a few pages of extra RAM :-)
