Apparatuses and methods for dynamic targeted refresh steals

Last updated:

Abstract:

Embodiments of the disclosure are drawn to apparatuses, systems, and methods for dynamic targeted refresh steals. A memory bank may receive access commands and then periodically enter a refresh mode, where auto-refresh operations and targeted refresh operations are performed. The memory bank may receive a refresh management command based on a count of access commands directed to the memory bank. Responsive to the refresh management signal, a panic targeted refresh operation may be performed on the memory bank. A number of times the refresh management signal was issued may be counted, and based on that count a next periodic targeted refresh operation may be skipped.
