Claim 14:
15. 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;
a second inverter, coupled to the first inverter to form a first latch for latching an output of the first inverter; and
a reset circuit, resetting the first latch for detection of a next power glitch.
