Abstract:
1. An internal voltage generation circuit comprising: a driving signal generator configured to compare 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 configured to generate 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 configured to compare the first internal voltage signal with the second internal voltage signal to generate a selection signal; and a selection transmitter configured to transmit any one of the first and second voltages to the first or second internal voltage signal in response to the selection signal, wherein the selection signal has a first level when the first internal voltage signal has a lower voltage level than the second internal voltage signal, and a second level when the first internal voltage signal has a higher voltage level than the second internal voltage signal.
