Abstract
This application is directed to methods and devices of detecting and correcting a fault in an integrated circuit. A latching circuit outputs a first voltage level at an output, and a function control signal is generated to hold the first voltage level outputted by the latching circuit. A single event upset originates within the latching circuit and causes the first voltage level at the output of the latching circuit to transition to a second voltage level. When the single event upset is detected, the latching circuit is controlled via a clear signal to reset its output to the first voltage level. A glitch is thereby formed on the first voltage level at the output of the latching circuit. The glitch is suppressed at the output of the latching circuit to generate the function control signal holding the first voltage level without the glitch.
