Abstract

See full text

An electronic system includes a main chip, a non-volatile storage circuit, and a detector circuit. The main chip is configured to read first time of a clock circuit. The non-volatile storage circuit is coupled to the main chip. The main chip stores the first time into the non-volatile storage circuit. The detector circuit includes a first output terminal. The first output terminal is coupled to the main chip. When a cold boot event occurs, the main chip reads the first time from the non-volatile storage circuit, and determines a reason of the cold boot event according to the first time, a second time of the clock circuit, and a logic value at the first output terminal.
