The constant reduction in memory cell sizes has increased memory density and reduced power consumption, but has also affected its reliability. The Rowhammer attack exploits this reduced reliability to induce bit flips in memory, without directly accessing these bits. Most Rowhammer attacks target software integrity, but some recent attacks demonstrated its use for compromising confidentiality.
