QPRAC: Towards Secure and Practical PRAC-based Rowhammer Mitigation using Priority Queues
JEDEC has introduced the Per Row Activation Counting (PRAC) framework for DDR5 and future DRAMs to enable precise counting of DRAM row activations. PRAC enables a holistic mitigation of Rowhammer atta...

DAPPER: A Performance-Attack-Resilient Tracker for RowHammer Defense
RowHammer vulnerabilities pose a significant threat to modern DRAM-based systems, where rapid activation of DRAM rows can induce bit-flips in neighboring rows. To mitigate this, state-of-the-art host-...
