  Rowhammer poses a significant security challenge for modern computers,
specifically affecting Dynamic Random Access Memory(DRAM). Given society's
growing reliance on computer systems, ensuring the reliability of hardware is
of utmost importance. This paper provides a comprehensive survey of Rowhammer,
examining the literature from various angles. We categorise studies on
Rowhammer into attacks, defences, and intriguing work, exploring each category
in detail. Furthermore, we classify papers within each category into distinct
yet overlapping classes and present an overview of the papers in each class.
