    • A semiconductor circuit includes a voltage pump, which has a series circuit of capacitors. The voltage pump furthermore has first switching elements, which are coupled between, in each case, two capacitors of the series circuit, and are coupled to capacitor electrodes of the capacitors by coupling lines. Connection lines are coupled to a respective connecting line and, in each case, have a second switching element, which enables an interruption of the respective connection line. It is possible for the second switching elements to be jointly switched to a conducting state when all the first switching elements are switched to a non-conducting state, as a result of which each capacitor is electrically charged individually by in each case two connection lines. It is also possible for the first switching elements to be jointly switched to a conducting state when all the second switching elements are switched to a non-conducting state, as a result of which all the electrically charged capacitors are electrically connected to one another.
    • 半导体电路包括具有电容器串联电路的电压泵。 电压泵还具有第一开关元件,其在每种情况下都耦合在串联电路的两个电容器中,并且通过耦合线耦合到电容器的电容器电极。 连接线耦合到相应的连接线,并且在每种情况下都具有第二开关元件,其能够中断相应的连接线。 当所有第一开关元件被切换到非导通状态时,第二开关元件可能共同切换到导通状态,结果,每个电容器在每种情况下通过两条连接线单独地充电。 当所有第二开关元件都切换到非导通状态时,第一开关元件也可以共同切换到导通状态,其结果是所有带电荷的电容器彼此电连接。
