1. A power-up signal generation circuit comprising:
a control signal generation unit suitable for generating first and second control voltages based on a power-up signal; a level tracing voltage generation unit suitable for generating a level tracing voltage with a voltage level that varies based on the first and second control voltages; and a power-up signal generation unit suitable for generating the power-up signal based on the level tracing voltage, and providing feedback on the power-up signal to the control signal generation unit, wherein the first control voltage is initialized to a first voltage and the second control voltage is initialized to a second voltage before the power-up signal is activated, and wherein the voltage levels of the first and second control voltages are inverted, respectively, whenever the power-up signal toggles after the power-up signal is activated.
