- addaon 3y agoSingle event upsets are well-understood and easy (although not necessarily cheap) to mitigate in hardware -- ECC for RAM, CRCs for data in flight, and voting (or lockstep if detection is sufficeint) for computation. The challenge with Rowhammer is that it involves multiple, correlated bit flips; and depending on details of your system the correlations may be disguised by various remapping layers.
