Abstract
Methods, apparatuses, and systems for staggering refresh operations to memory arrays in different dies of a three-dimensional stacked (3DS) memory device are described. A 3DS memory device may include one die or layer of that controls or regulates commands, including refresh commands, to other dies or layers of the memory device. For example, one die of the 3DS memory may delay a refresh command when issuing the multiple concurrent memory refreshes would cause some problematic performance condition, such as high peak current, within the memory device.
