Abstract
A system to progressively generate responses configured to mitigate risk associated with row hammer attacks. Between two successive refreshing of memory cells in a memory device, increasing thresholds are used to detect row hammer attacks. For example, after a first alert of row hammer attacks is generated using a first lower threshold, a first operation associated with the first lower threshold is initiated to mitigate risk associated with row hammer attack; and a second higher threshold is used to detect row hammer attacks. After a second alert of row hammer attacks is generated using the second lower threshold, a second operation associated with the second lower threshold is initiated to mitigate risk associated with row hammer attack.
