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

Rowhammer-induced bit-flips are a threat to DRAM security. To mitigate Rowhammer,
DDR4 devices employ TRR, an in-DRAM tracker, to identify aggressor rows. In-DRAM …

The Rowhammer vulnerability is worsening, with the Rowhammer Threshold (T RH)
reducing from 139K to 4.8 K activations over the last decade. As thresholds reduce further …

To understand and improve DRAM performance, reliability, security, and energy efficiency,
prior works study characteristics of commodity DRAM chips. Unfortunately, state-of-the-art …

In computer architecture studies, simulators are crucial for design verification, reducing
research and development time and ensuring the high accuracy of verification results …

This paper investigates secure low-cost in-DRAM trackers for mitigating Rowhammer (RH).
In-DRAM solutions have the potential to solve the RH problem within the DRAM chip without …

Modern systems mitigate Rowhammer using victim refresh, which refreshes neighbours of
an aggressor row when it encounters a specified number of activations. Unfortunately …

Error-correcting code (ECC) has been widely used in DRAM-based memory systems to
address the exacerbating random errors following the fabrication process scaling. However …

Read disturbance in modern DRAM chips is a widespread phenomenon and is reliably used
for breaking memory isolation, a fundamental building block for building robust systems …

DRAM vendors do not disclose the architecture of the sense amplifiers deployed in their
chips. Unfortunately, this hinders academic research that focuses on studying or improving …
