DRAM is the most prevalent memory technology used in laptops, mobile phones, workstations and servers. As such, its security is paramount, yet DRAM attacks remain as viable as ever despite many attempts to resolve its security problems. The toolkit of DRAM disturb attacks has expanded with the introduction of new techniques such as Half-Double, RowPress, and ColumnDisturb, and it is likely that additional form of disturbance errors (and reliability and security issues) will emerge as we scale DRAM devices to smaller feature sizes. DRAM is also plagued by additional forms of attack, including side-channel, Denial-of-Service (DoS), and cold-boot attacks.

Against this backdrop, the industry is introducing new DRAM security solutions that require independent scrutiny from the academia. Academia continues to propose novel fixes for RowHammer, often without the benefit of insight into constraints faced by the industry.
