Cleaning up the Mess: Re-Evaluating the Real-System Modeling Accuracy of Ramulator 2.0
F. Nisa Bostanci, Haocong Luo, Ataberk Olgun +4
A MICRO 2024 best paper runner-up publication (the Mess paper) with all three artifact badges awarded (including ``Reproducible'') proposes a new benchmark to evaluate real and sim…
RevaMp3D: Architecting the Processor Core and Cache Hierarchy for Systems with Monolithically-Integrated Logic and Memory
Nika Mansouri Ghiasi, Mohammad Sadrosadati, Geraldo F. Oliveira +11
Recent nano-technological advances enable the Monolithic 3D (M3D) integration of multiple memory and logic layers in a single chip, allowing for fine-grained connections between la…
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…
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…
New Tools, Programming Models, and System Support for Processing-in-Memory Architectures
Geraldo F. Oliveira
Our goal in this dissertation is to provide tools, programming models, and system support for PIM architectures (with a focus on DRAM-based solutions), to ease the adoption of PIM…
Proteus: Enabling High-Performance Processing-Using-DRAM with Dynamic Bit-Precision, Adaptive Data Representation, and Flexible Arithmetic
Geraldo F. Oliveira, Mayank Kabra, Yuxin Guo +8
Processing-using-DRAM (PUD) is a paradigm where the analog operational properties of DRAM are used to perform bulk logic operations. While PUD promises high throughput at low energ…
