Abstract
Row hammer attacks takes advantage of unintended and undesirable side effects of memory devices in which memory cells interact electrically between themselves by leaking their charges and possibly changing the contents of nearby memory rows that were not addressed in an original memory access. Row hammer attacks are mitigated by using a victim cache. Data is written to cache lines of a cache. A least recently used cache line of the cache is written to the victim cache.
