While recent PRAC implementations enable holistic mitigation of Rowhammer attacks, they impose slowdowns of up to 10% due to the increased DRAM timings for performing a read-modify-write of the counter. Alternatively, recent work, Chronus, addresses these slowdowns, but incurs energy overheads due to the additional DRAM activations for counters.
