PULSAR: Simultaneous Many-Row Activation for Reliable and High-Performance Computing in Off-the-Shelf DRAM Chips
Ismail Emir Yuksel, Yahya Can Tugrul, F. Nisa Bostanci +8
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 obstacle, P…
Read Disturbance in High Bandwidth Memory: A Detailed Experimental Study on HBM2 DRAM Chips
Ataberk Olgun, Majd Osseiran, Abdullah Giray Yaglikci +6
We experimentally demonstrate the effects of read disturbance (RowHammer and RowPress) and uncover the inner workings of undocumented read disturbance defense mechanisms in High Ba…
DaPPA: A Unified Data-Parallel Programming Framework for Efficient Processing-in-Memory Execution
Geraldo F. Oliveira, Alain Kohli, David Novo +5
Processing-in-memory (PIM) alleviates data-movement bottlenecks by placing computation near or inside memory. Two general-purpose PIM paradigms are now practical: processing-near-m…
ABACuS: All-Bank Activation Counters for Scalable and Low Overhead RowHammer Mitigation
Ataberk Olgun, Yahya Can Tugrul, Nisa Bostanci +6
We introduce ABACuS, a new low-cost hardware-counter-based RowHammer mitigation technique that performance-, energy-, and area-efficiently scales with worsening RowHammer vulnerabi…
Ramulator 2.0: A Modern, Modular, and Extensible DRAM Simulator
Haocong Luo, Yahya Can Tuğrul, F. Nisa Bostancı +3
We present Ramulator 2.0, a highly modular and extensible DRAM simulator that enables rapid and agile implementation and evaluation of design changes in the memory controller and D…
RowPress: Amplifying Read Disturbance in Modern DRAM Chips
Haocong Luo, Ataberk Olgun, A. Giray Yağlıkçı +6
Memory isolation is critical for system reliability, security, and safety. Unfortunately, read disturbance can break memory isolation in modern DRAM chips. For example, RowHammer i…
An Experimental Analysis of RowHammer in HBM2 DRAM Chips
Ataberk Olgun, Majd Osseiran, Abdullah Giray Ya{ğ}lık{c}ı +6
RowHammer (RH) is a significant and worsening security, safety, and reliability issue of modern DRAM chips that can be exploited to break memory isolation. Therefore, it is importa…
