Apparatuses and methods for staggered timing of targeted refresh operations

Abstract:

Embodiments of the disclosure are drawn to apparatuses and methods for staggering the timing of targeted refresh operations. A memory device may include a number of memory banks, at least some of which may be simultaneously entered into a refresh mode. A given memory bank may perform an auto-refresh operation or a targeted refresh operation, which may draw less power than the auto-refresh operation. The timing of the targeted refresh operations may be staggered between the refreshing memory banks, such that a portion of the refreshing memory banks are performing a targeted refresh operation simultaneously with a portion of the refreshing memory banks performing an auto-refresh operation.
