Abstract
Apparatuses, systems, and methods for controller directed targeted refresh operations. A memory may be coupled to a controller. The memory may identify aggressor addresses based on sampled addresses. The addresses may be sampled based on internal timing logic of the memory and also based on a sampling command received from the controller. The memory may also receive a controller identified aggressor address from the controller. The memory may refresh one or more victim word lines of the identified (either by the memory or the controller) aggressor addresses as part of a targeted refresh operation. Victims of controller identified aggressor addresses may be refreshed before memory identified aggressor addresses.
