摘要：Apparatuses, systems, and methods for refresh modes. A memory may need to
perform targeted refresh operations to refresh the ‘victim’ word lines which are near to frequently accessed ‘aggressor’ word lines. To refresh the victims at a high enough rate, it may be desirable to refresh multiple victims as part of the same refresh operation. However, certain word lines (e.g., word lines in a same section or adjacent sections of the memory) cannot be refreshed together. The memory may have a section comparator, which may check stored aggressor addresses and may provide a signal if there are not two stored addresses which can be refreshed together. Based, in part, on the signal, the memory may activate one of several different refresh modes, which may control the types of refresh operation performed responsive to a refresh signal.
