Are there any performance related effects of using radiation hardened memory units as compared to non-hardened ones having the same configuration except the protection it should provide from radiation damage? (read write speed, date reliability)

RADHARD ICs generally have a dual encoding and a parity; however, some encode 4 bits as 6 bits so that you have encoding schemes where you are fine even if you lose a bit. Without giving the specific IC, I can say that you'll most likely use more power, but the biggest issue is that these IC cost much more.
