Abstract
An inverter circuit includes a pull-up control circuit and a pull-up drive circuit. The pull-up control circuit generates a drive signal which is enabled during a first time period in response to an input signal and an output signal. The pull-up drive circuit drives the output signal to a power supply voltage in response to the input signal and the drive signal. The pull-up drive unit drives the output signal with a first drivability during the first time period and drives the output signal with a second drivability during a second time period.
