PVAC mitigates RowHammer by incrementing counters on victim rows and resetting them on activation via a parallel counter subarray, avoiding PRAC's saturation and timing penalties while supporting higher hammering tolerance.

PVAC: A RowHammer Mitigation Architecture Exploiting Per-victim-row Counting
PVAC mitigates RowHammer by incrementing counters on victim rows and resetting them on activation via a parallel counter subarray, avoiding PRAC's saturation and timing penalties while supporting higher hammering tolerance.
