Abstract:
Memory devices with controlled wordline ramp rates and associated systems and methods are disclosed herein. In one embodiment, a memory device includes at least one voltage regulator and a plurality of wordlines. The memory device is configured, during a programming operation of the memory region, to ramp a selected wordline to a desired programming voltage while ramping one or more adjacent, unselected wordlines electrically coupled to the selected wordline to desired inhibit voltage(s) using the at least one voltage regulator. In some embodiments, the memory device ramps the selected wordline and the one or more adjacent, unselected wordlines such that the one or more adjacent, unselected wordlines reach the desired inhibit voltage(s) when the selected wordline reaches the desired programming voltage. In these and other embodiments, the memory device ramps the selected wordline to the desired programming voltage without floating the selected wordline.
