HammerSim: A Tool to Model Rowhammer
Local Download Presentation Download Repository
Recently the rowhammer vulnerability has affected modern memory devices, which allows an attacker to cause bitflips without accessing the corresponding cell. The rowhammer effects can exacerbate future memory technologies due to scaling. Hence, we need to invest in studying and mitigating rowhammer attacks. We, therefore, propose a model to simulate RowHammer in gem5 to capture the system-level interaction of RowHammer.
