Implementation of Rowhammer Effect in gem5

Modern computer memories have been shown to have reliability issues. The main memory is the target of a se-curity attack called Rowhammer, which causes bit flips in adjacent victim cells of aggressor rows. Existing architec-tures simulator don’t provide any implementation of unin-tended memory modifications like bit-flips. In this paper, we propose an implementation of the Rowhammer effect in the gem5 architecture simulator.
