Abstract
A resistive memory device requires a power supply having a reduced number of voltage taps and reduced power consumption. In accordance with one exemplary embodiment, one or more voltages used by a reference circuit which are normally supplied by different taps of a power supply are generated by corresponding power circuits. In accordance with a second exemplary embodiment, the power circuits are coupled to the bit lines and replace the reference circuit in a manner to improve sensing margin.
