[MURG] Uploading via memory implants?

[Giu1i0 Pri5c0]

When the tech of brain implants is perfected (e.g.
http://www.cyberkineticsinc.com/index.htm), could it evolve in
practical means for uploading?
Suppose one implants a memory extension that can be interfaced to the
biological brain and store memories. If memories are not localized but
scattered all over the brain, it seems plausible that after some time
enough memory components have migrated to the new memory support and
can be retrieved with apropriate tech.
I am sure there must have been studies on this.
