Rowhammer is a hardware vulnerability that affects DRAM memory chips and can be exploited to modify memory contents, potentially providing root access to the system. It occurs because Dynamic RAM consists of multiple memory cells packed tightly together and specific access patterns can cause unwanted effects that propagate to nearby ... WebRowhammer DRAM vulnerability: a brief note DRAM Architecture I DRAM is hierarchically composed of Channels, Rank and Banks.
