ColumnKeeper: Efficient Solutions to the ColumnDisturb Vulnerability in DRAM-based Systems
Andreas Kosmas Kakolyris, F. Nisa Bostanci, Ataberk Olgun +7
Modern DRAM chips are vulnerable to read disturbance phenomena such as RowHammer and RowPress, which induce bitflips after accessing nearby rows a certain number of times (the read…
DiscoRD: An Experimental Methodology for Quickly Discovering the Reliable Read Disturbance Threshold of Real DRAM Chips
Ataberk Olgun, F. Nisa Bostanci, Ismail Emir Yuksel +4
State-of-the-art DRAM read disturbance mitigations rely on the read disturbance threshold (RDT) (e.g., the number of aggressor row activations needed to induce the first read distu…
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, Oğuzhan 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…
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…
TuRaN: True Random Number Generation Using Supply Voltage Underscaling in SRAMs
İsmail Emir Yüksel, Ataberk Olgun, Behzad Salami +6
Prior works propose SRAM-based TRNGs that extract entropy from SRAM arrays. SRAM arrays are widely used in a majority of specialized or general-purpose chips that perform the compu…
