Cache Line Pinning for Mitigating Row Hammer Attack

RowHammer attack is a serious security threat to DRAM-based memory that causes bit flips in nearby rows when a DRAM row is accessed frequently. Many mitigation strategies are proposed against the RowHammer attack, and a few of the mitigation strategies are adopted and implemented by the hardware vendors. But even the latest generations of DRAM-based memory with in-DRAM mitigation are found vulnerable to the RowHammer attack.
