An exemplary power control circuit includes a scaler circuit configured for outputting a control signal, a voltage converter configured for converting a received voltage into a plurality of desired voltages, a first control unit, a second control unit, and a coupling circuit. In the nonvolatile memory device, a blocking insulation layer is provided between a trap insulation layer and a gate electrode. An evaluation processor calculates evaluation values corresponding to specified search movements, thus extracting a minimum evaluation value among as many evaluation values as the number of search movements performed. Specifically, the different fields are used as tagged element of the XML document. At least one electrode terminates within the bed at a distance from earthed supporting structure to avoid or reduce the risk of tracking or arcing between the electrode and the supporting structure. When the forwarding system encounters such an instruction during compilation of the class definition, the forwarding system provides an implementation of each virtual function of the interface that forwards its invocation to a corresponding virtual function in the implementing class.
