Work-in-Progress: DRAM-MaUT: DRAM Address Mapping Unveiling Tool for ARM Devices
Anandpreet Kaur, Pravin Srivastav, Bibhas Ghoshal · 2022
In this paper, we propose a software based technique to reveal the DRAM geometry information which is essential in studying various memory based attacks mounted on embedded devices such as Row Hammer. We apply a reverse-engineering approach for retrieving row, column, bank bits of DRAM which may significantly increase the number of bit flips in a Row Hammer test. To the best of our knowledge, the proposed technique is the first work to disclose the entire information about the DRAM chips of any embedded architecture.
