In-DRAM True Random Number Generation Using Simultaneous Multiple-Row Activation: An Experimental Study of Real DRAM Chips
Ismail Emir Yuksel, Ataberk Olgun, F. Nisa Bostanci +5
In this work, we experimentally demonstrate that it is possible to generate true random numbers at high throughput and low latency in commercial off-the-shelf (COTS) DRAM chips by…
Understanding and Mitigating Covert Channel and Side Channel Vulnerabilities Introduced by RowHammer Defenses
F. Nisa Bostancı, OÄuzhan Canpolat, Ataberk Olgun +5
DRAM chips are vulnerable to read disturbance phenomena (e.g., RowHammer and RowPress), where repeatedly accessing or keeping open a DRAM row causes bitflips in nearby rows. Attack…
Chronus: Understanding and Securing the Cutting-Edge Industry Solutions to DRAM Read Disturbance
OÄuzhan Canpolat, A. Giray YaÄlıkçı, Geraldo F. Oliveira +6
We 1) present the first rigorous security, performance, energy, and cost analyses of the state-of-the-art on-DRAM-die read disturbance mitigation method, Per Row Activation Countin…
EasyDRAM: An FPGA-based Infrastructure for Fast and Accurate End-to-End Evaluation of Emerging DRAM Techniques
OÄuzhan Canpolat, Ataberk Olgun, David Novo +2
DRAM is a critical component of modern computing systems. Recent works propose numerous techniques (that we call DRAM techniques) to enhance DRAM-based computing systems' throughpu…
PuDHammer: Experimental Analysis of Read Disturbance Effects of Processing-using-DRAM in Real DRAM Chips
Ismail Emir Yuksel, Akash Sood, Ataberk Olgun +6
Processing-using-DRAM (PuD) is a promising paradigm for alleviating the data movement bottleneck using DRAM's massive internal parallelism and bandwidth to execute very wide operat…
Variable Read Disturbance: An Experimental Analysis of Temporal Variation in DRAM Read Disturbance
Ataberk Olgun, F. Nisa Bostanci, Ismail Emir Yuksel +6
Modern DRAM chips are subject to read disturbance errors. State-of-the-art read disturbance mitigations rely on accurate and exhaustive characterization of the read disturbance thr…
