DRAM based memory-centric computing architectures are promising solutions to tackle the
challenges of memory wall. In this paper, we develop a novel design of DRAM-based …

Modern computing systems access data in main memory at coarse granularity (eg, at 512-bit
cache block granularity). Coarse-grained access leads to wasted energy because the …

As recently emerged rowhammer exploits require undocumented DRAM address mapping,
we propose a generic knowledge-assisted tool, DRAMDig, which takes domain knowledge …

DRAM cells in close proximity can fail depending on the data content in neighboring cells.
These failures are called data-dependent failures. Detecting and mitigating these failures …

DRAM is the most mature and widely-utilized memory structure as main memory in
computing systems. However, energy dissipation and latency of DRAM are two of the most …

Memory protection is necessary to ensure the correctness of data in the presence of
unavoidable faults. As such, large-scale systems typically employ Error Correcting Codes …

DRAM technology scaling has the undesirable side effect of degrading cell reliability. One
such concern of deeply scaled DRAMs is the increased coupling between adjacent cells …

Rowhammer is a vulnerability that arises due to the undesirable interaction between
physically adjacent rows in DRAMs. Existing DRAM protections are not adequate to defend …

Data movement between the processor and the main memory is a first-order obstacle
against improving performance and energy efficiency in modern systems. To address this …

Poor DRAM technology scaling over the course of many years has caused DRAM-based
main memory to increasingly become a larger system bottleneck. A major reason for the …
