While Sony has not come forward with complete CPU footprint information, they've stated that PlayStation Move requires an "insignificant" 1-2MB of RAM.

But like we said, CPU processing has plenty to do with Move's digital footprint, too. And just because the Move's output can be processed in "under a frame" doesn't mean the graphics, physics and overall experience of said frame aren't diminished. [Joystiq]
