MORDOR:Mitigating Overheads of Read Disturbance Preventive Operations via Elastic Refresh Scheduling
MORDOR is a new policy that intelligently delays preventive refresh operations (PROs) to run outside of critical memory access paths. It leverages the fact that a PRO targeting one row can be postponed if no other demand request accesses that aggressor row. This reduces system performance degradation and energy consumption caused by high volumes of PROs.
