Abstract
Power is routed from one or more power supplies. As consistent with one or more example embodiments, a data storage device senses and/or is informed of the availability and voltage level of one or more power supplies. Based upon the availability and voltage level of power supplies, circuits in the memory device are powered using one or more of the sensed power supplies. In some applications, the power is drawn in a manner that emulates the behavior of one or more circuits that are respectively powered.
