Abstract
Apparatuses, systems, and methods for access based targeted refresh operations. A memory bank has a first sub-bank and a second sub-bank. A refresh control circuit detects an aggressor in one of the sub-banks. Responsive to an access in the other sub-bank, the refresh control circuit performs a targeted refresh operation based on the sub-bank based on the aggressor address.
