  • Publication number: 20240354262
    Abstract: Aspects of the present disclosure relate to techniques for minimizing the effects of RowHammer and induced charge leakage. In examples, systems and methods for preventing access pattern attacks in random-access memory (RAM) are provided. In aspects, a data request associated with a page table may be determined to be a potential security risk and such potential security risk may be mitigated by randomly selecting a memory region from a subset of memory regions, copying data stored in a memory region associated with a page table entry in the page table to the second memory region, disassociating the second memory region from the subset of memory regions and associating the memory region associated with the page table to the second memory region, and updating the page table entry in the page table to refer to the second memory region.
