DRAM Bender: An Extensible and Versatile FPGA-based Infrastructure to Easily Test State-of-the-art DRAM Chips
Ataberk Olgun, Hasan Hassan, A. Giray Yağlıkçı +6
To understand and improve DRAM performance, reliability, security and energy efficiency, prior works study characteristics of commodity DRAM chips. Unfortunately, state-of-the-art…
HiRA: Hidden Row Activation for Reducing Refresh Latency of Off-the-Shelf DRAM Chips
Abdullah Giray Yağlıkçı, Ataberk Olgun, Minesh Patel +5
DRAM is the building block of modern main memory systems. DRAM cells must be periodically refreshed to prevent data loss. Refresh operations degrade system performance by interferi…
Sectored DRAM: A Practical Energy-Efficient and High-Performance Fine-Grained DRAM Architecture
Ataberk Olgun, F. Nisa Bostanci, Geraldo F. Oliveira +6
We propose Sectored DRAM, a new, low-overhead DRAM substrate that reduces wasted energy by enabling fine-grained DRAM data transfers and DRAM row activation. Sectored DRAM leverage…
Self-Managing DRAM: A Low-Cost Framework for Enabling Autonomous and Efficient in-DRAM Operations
Hasan Hassan, Ataberk Olgun, A. Giray Yaglikci +2
The memory controller is in charge of managing DRAM maintenance operations (e.g., refresh, RowHammer protection, memory scrubbing) to reliably operate modern DRAM chips. Implementi…
Understanding RowHammer Under Reduced Wordline Voltage: An Experimental Study Using Real DRAM Devices
A. Giray Yağlıkçı, Haocong Luo, Geraldo F. de Oliviera +7
RowHammer is a circuit-level DRAM vulnerability, where repeatedly activating and precharging a DRAM row, and thus alternating the voltage of a row's wordline between low and high v…
PiDRAM: An FPGA-based Framework for End-to-end Evaluation of Processing-in-DRAM Techniques
Ataberk Olgun, Juan Gomez Luna, Konstantinos Kanellopoulos +4
DRAM-based main memory is used in nearly all computing systems as a major component. One way of overcoming the main memory bottleneck is to move computation near memory, a paradigm…
DR-STRaNGe: End-to-End System Design for DRAM-based True Random Number Generators
F. Nisa Bostancı, Ataberk Olgun, Lois Orosa +5
Random number generation is an important task in a wide variety of critical applications including cryptographic algorithms, scientific simulations, and industrial testing tools. T…
