Memory devices are disclosed that support multiple power ramping sequences or modes. For example, a level shifter device is operably connected to a memory macro in a memory device. The level shifter device receives at least one gating signal. Based on a state of the at least one gating signal, the level shifter device outputs one or more signals that cause or control voltage signals in or received by the memory macro to ramp up, ramp down, or ramp up and ramp down according to one or more power ramping modes.
