Abstract
A semiconductor device includes a boot-up start signal generation unit configured to generate a boot-up start signal which is enabled in synchronization with a time at which a preset delay period has passed from a time point at which an initialization signal is enabled after a power-up period is ended, and a boot-up period signal generation unit configured to generate a boot-up period signal which is enabled according to a set pulse generated in synchronization with a time point at which the boot-up start signal is enabled.
Claims10
A semiconductor device comprising:
- a signal combination section configured to generate a combined power-up signal in response to a power-up signal enabled after a power-up period is ended and an initialization signal;
- a control signal generation section configured to generate an oscillator control signal in response to the combined power-up signal and to generate a boot-up start signal in response to a count output signal;
- and
- a counter output signal generation section configured to generate an oscillation signal in response to the oscillator control signal, and to generate a count output signal by performing a counting operation in synchronization with the oscillation signal.
