Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for distributed timing of targeted refresh operations. Information stored in volatile memory cells may decay unless refresh operations are performed. A memory device may perform auto-refresh operations, as well as one or more types of targeted refresh operations, where particular rows are targeted for a refresh. Targeted refresh operations may draw less power than an auto-refresh operation. It may be desirable to distribute targeted refresh operations throughout a sequence of refresh operations, to average out a power draw in the memory device. Responsive to an activation of a refresh signal, the memory device may perform a group of refresh operations. At least one refresh operation in each group may be a targeted refresh operation.
