A semiconductor switching device includes two FETs with different device characteristics, a common input terminal, and two output terminals. The fuel line permits fuel to flow from both tanks to a common fuel suction line, which, in turn, feeds the vehicle’s engine with fuel. The column address latch circuit holds the column address which has already been input when the active command is input, in synchronism with a control signal which is generated when either a read command or a write command is input. The system also provides a charging mechanism configured to selectively charge each of the plurality of conductive elements on the first semiconductor die, wherein charging a conductive element on the first semiconductor die induces a charge in one or more conductive elements on the second semiconductor die. A method of providing advertising content includes conducting an activity involving participants; receiving input regarding the participants engaged in the activity; and displaying advertising content from a database concurrently with information regarding the activity. In a preferred embodiment, the concentration of Ge is between 15% and 18%, the concentration of Sb is between 32% and 35%, and the concentration of Te is between 48% and 51%.
