摘要：
A low voltage detection circuit includes a first detection block configured to detect a level of an external voltage according to a reference voltage, and output a pre-detection signal; and a second detection block configured to generate a low voltage detection signal of a beginning level regardless of a variation in a level of the pre-detection signal when the level of the pre-detection signal is detected as the beginning level.
