摘要： A power circuit includes a reference potential circuit, a step-up circuit, and a conversion circuit. The reference potential circuit generates a reference potential. The step-up circuit generates a desired internal potential by stepping up a power supply potential. The step-up circuit includes a comparison circuit, a differential amplifier circuit, and a switch element. The comparison circuit outputs the result of comparison between a potential and the reference potential. The differential amplifier circuit is turned on or off by the operation control signal. The switch element performs on/off control according to the operation control signal and resets the output potential of the differential amplifier circuit. The conversion circuit converts the of the operation control signal so as to make longer the on period of the differential amplifier circuit and the off period of switch element.

摘要： According to one embodiment, provided is a semiconductor boost circuit including a pump circuit, a switch signal generating circuit and a clock signal generating circuit. The pump circuit receives a clock signal and performs charge pump operation on the basis of the clock signal to boost an input potential to a set potential. The switch signal generating circuit outputs CLK cycle switch signal when a potential output by the pump circuit reaches a first potential greater than the input potential and less than the set potential. The clock signal generating circuit outputs the clock signal having a first frequency if not receiving the CLK cycle switch signal, and, on the other hand, outputs the clock signal having a second frequency greater than the first frequency if receiving the CLK cycle switch signal.
摘要翻译：根据一个实施例，提供了包括泵电路，开关信号发生电路和时钟信号发生电路的半导体升压电路。泵电路接收时钟信号，并且基于时钟信号执行电荷泵操作，以将输入电位升高到设定电位。当泵电路的电位输出达到大于输入电位并小于设定电位的第一电位时，开关信号发生电路输出CLK周期开关信号。如果不接收到CLK周期切换信号，则时钟信号发生电路输出具有第一频率的时钟信号，另一方面，如果接收到CLK周期切换信号，则输出具有大于第一频率的第二频率的时钟信号。
