Abstract
In some examples, a memory device may perform refresh operations responsive to internal and/or external commands. internal refresh commands may include auto-refresh commands and row hammer (e.g., targeted) refresh commands. External commands may include refresh management commands. In some examples, the external command may cause a refresh operation to occur after a number of activation commands. The memory device may monitor row addresses associated with the activation commands. In some examples, the memory device may skip a refresh operation indicated by a refresh management command if none of the row addresses associated with the activation commands occurs at a high frequency. In some examples, row addresses may be determined to be aggressor row addresses if a received row address matches a previously received row address.
