Abstract
A memory area is protected from rowhammer attacks by placing an extra sacrificial row at the top and the bottom of the memory addresses defining the area to be protected. The sacrificial rows of memory are written with a known bit pattern that may be read periodically to detect any rowhammer attacks that may be in progress.
