Claim 13:
14. A chip with power-glitch detection, comprising:
a power terminal, receiving power;
a first inverter having an input terminal coupled to the power terminal; and
a back-up power storage device coupled to the power terminal, transforming the power to back-up power, wherein the first inverter is powered by the back-up power when a power glitch occurs on the power terminal, and the power glitch is reflected at an output terminal of the first inverter; and
a D flip-flop, having a D terminal coupled to the output terminal of the first inverter, a clock terminal coupled to the power terminal, and a Q terminal,
wherein the power glitch is detected when the Q terminal of the D-flip-flop is at a high level.
