Just ran out of "Device Memory" space on my v1 Note (N7000, Android 4.0.4) . Auto-update of some app or another failed with insufficient space in "Device Memory" - which shows up as having a total space of only 1.97 gigs. I cleaned house by uninstalling every app that I could find that had not been used recently and now it's OK.... But that's only now.... System Settings | Storage does, indeed, show Device Memory - along with USB Storage and SD Card. I'm guessing that "SD Card" is the 64-gig class 10 micro SD that I have in there and "USB Storage" (11.07 gigs) is some sort of hard-wired SD card analog. But what is "Device Memory"? More to the point.... Is there any way that I can force Android to install new apps on to the 64-gig micro SD... or even the "SD Card" instead of pigging up that very limited "Device Memory"? Could "Device Memory" be just a partition of the same physical memory that is "USB Storage"? On my 10.1" Note (Jellybean...) I see that there is no distinction between "Device Memory" and "USB Storage".... so maybe all this is moot in the context of the soon-to-come (?) upgrade to Jellybean on the N7000. ??
