    • A voltage supply circuit includes a first holding element with a first end and a second end that supplies a voltage held between the first end and the second end to a load, the second end being connected to a ground, and a second holding element with a first end and a second end, the first end of the second holding element being electrically connected to the first end of the first holding element. The voltage supply circuit also includes a charging circuit that charges the second holding element with a voltage higher than the voltage to be supplied to the load in a first mode, and a potential adjusting circuit that shifts a potential at the second end of the second holding element towards a potential at the first end of the first holding element according to the voltage held by the first holding element or the second holding element in a second mode exclusive with respect to the first mode.
    • 电压供应电路包括具有第一端的第一保持元件和将第一端和第二端之间保持的电压提供给负载的第二端,第二端连接到地,以及第二保持元件,其具有 第一端和第二端,第二保持元件的第一端电连接到第一保持元件的第一端。 电压供给电路还包括充电电路,其以比在第一模式中提供给负载的电压高的电压对第二保持元件充电,以及电位调整电路,其将第二保持的第二端的电位移位 元件朝向第一保持元件的第一端处的电位,根据第一保持元件或第二保持元件以第二模式保持的电压相对于第一模式排除。
