    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.

    Abstract: Disclosed herein are related to a memory device including a set of memory cells and a memory controller. In one aspect, each of the set of memory cells includes a select transistor and a storage element connected in series between a corresponding bit line and a corresponding source line. In one aspect, the memory controller is configured to apply a first write voltage to a bit line coupled to a selected memory cell, apply a second write voltage to a word line coupled to a gate electrode of a select transistor of the selected memory cell during a first time period, and apply a third write voltage to a source line coupled to the selected memory cell. The second write voltage may be between the first write voltage and the third write voltage.
