A voltage control circuit of the present invention is applicable to a combination of a decoder circuit and a level conversion circuit connected to the decoder circuit. The voltage control circuit includes a level conversion circuit voltage line for applying a voltage to the level conversion circuit, and a boost voltage connection switch for switching a voltage applied to the level conversion circuit voltage line according to an output signal from the decoder circuit. This configuration makes it possible to prevent, when a boost voltage is applied to the level conversion circuit, the breakdown of transistors in the level conversion circuit due to a ripple in the boost voltage.
