    • Internal voltage generation circuits are provided. The internal voltage generation circuit includes a driving signal generator comparing first and second internal voltage signals with lower and upper limit reference voltage signals to generate a pull-up driving signal and a pull-down driving signal, a driver generating a first voltage and a second voltage in response to the pull-up driving signal and the pull-down driving signal, a selecting signal generator comparing the first internal voltage signal with the second internal voltage signal to generate a selection signal, and a selection transmitter that transmits any one of the first and second voltages to the first or second internal voltage signal in response to the selection signal.
    • 提供内部电压发生电路。 内部电压产生电路包括驱动信号发生器,其将第一和第二内部电压信号与下限和上限参考电压信号进行比较,以产生上拉驱动信号和下拉驱动信号,产生第一电压的驱动器和第二电压 响应于上拉驱动信号和下拉驱动信号的电压;选择信号发生器,将第一内部电压信号与第二内部电压信号进行比较以产生选择信号;以及选择发送器,其将任何一个 第一和第二电压响应于选择信号到第一或第二内部电压信号。
