Just throwing this out there, but could it be virtual memory? I know computers do this (my mac has ~6GB of it) so maybe smartphones do this too. It could also be used for memory protection/ the fast boot thing. I know on my mac 4GB are used on the hard drive which are an exact copy of the DDR memory so that if the computer shuts off suddenly it can be restored and so that the sleep mode can use even less power. Maybe the quick boot thing on the Thunderbolt works the same way? Just some ideas.
