Memory isolation is critical for system reliability, security, and safety. Unfortunately, read disturbance can break memory isolation in modern DRAM chips. For example, RowHammer …
The RowHammer vulnerability in DRAM is a critical threat to system security. To protect against RowHammer, vendors commit to security-through-obscurity: modern DRAM chips …
Aggressive memory density scaling causes modern DRAM devices to suffer from RowHammer, a phenomenon where rapidly activating (ie, hammering) a DRAM row can …
RowHammer is a circuit-level DRAM vulnerability where repeatedly accessing (ie, hammering) a DRAM row can cause bit flips in physically nearby rows. The RowHammer …
Row Hammer is a fault-injection attack in which rapid activations to a single DRAM row causes bit-flips in nearby rows. Several recent defenses propose tracking aggressor-rows …

Secure hardware enclaves have been widely used for protecting security-critical applications in the cloud. However, existing enclave designs fail to meet the requirements of …
As Row Hammer (RH) attacks have been a critical threat to computer systems, numerous hardware-based (HWbased) RH mitigation strategies have been proposed. However, the …
The DRAM substrate is becoming increasingly more vulnerable to Rowhammer as we move to smaller technology nodes. We introduce ProTRR, the first principled in-DRAM Target Row …
RowHammer is a circuit-level DRAM vulnerability, where repeatedly activating and precharging a DRAM row, and thus alternating the voltage of a row's wordline between low …
