APPARATUSES, SYSTEMS, AND METHODS FOR CONTROLLER DIRECTED TARGETED REFRESH OPERATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18649696 titled 'APPARATUSES, SYSTEMS, AND METHODS FOR CONTROLLER DIRECTED TARGETED REFRESH OPERATIONS
The abstract describes apparatuses, systems, and methods for controller-directed targeted refresh operations in memory systems. The memory is connected to a controller and can identify aggressor addresses based on sampled addresses using internal timing logic and sampling commands from the controller. The memory can also receive aggressor addresses identified by the controller and perform targeted refresh operations on victim word lines associated with these addresses.

Original Abstract Submitted
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.
