Abstract
A semiconductor device includes a power-on reset circuit configured to receive a power voltage and generate a power-on reset signal varying with a voltage level of the power voltage, an internal circuit configured to be initialized and operated in response to the power-on reset signal and generate a hold signal based on an operation mode of the internal circuit, and a reset protection circuit configured to deactivate the power-on reset circuit in response to the hold signal and provide a replacement signal for replacing the power-on reset signal to the internal circuit when the power-on reset circuit is deactivated.
