JaceRem, both chips are the same package and it appears as if the circuitry is the same. It will require a reball, for that you will need the solder balls, stencil and rework station. Of course you will also need firmware supporting the higher memory. Not an easy task nor is it inexpensive. May be a USB hub and a USB storage device might be a better way to go.
