Memory isolation is critical for system reliability, security, and safety. Unfortunately, read
disturbance can break memory isolation in modern DRAM chips. For example, RowHammer …

We present the new class of non-uniform Rowhammer access patterns that bypass
undocumented, proprietary in-DRAM Target Row Refresh (TRR) while operating in a …

AMD has gained a significant market share in recent years with the introduction of the Zen
microarchitecture. While there are many recent Rowhammer attacks launched from Intel …

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 …

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 …

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 …

Aggressive memory density scaling causes modern DRAM devices to suffer from
RowHammer, a phenomenon where rapidly activating (ie, hammering) a DRAM row can …

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 …

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 …

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 …
