Abstract
Structures and methods are provided for performing non-destructive and secure disablement of integrated circuit (IC) functionality. A structure for enabling non-destructive and secure disablement and re-enablement of the IC includes a micro-electrical mechanical structure (MEMS) initially set to a chip enable state. The structure also includes an activation circuit operable to set the MEMS device to an error state based on a detected predetermined condition of the IC. The IC is disabled when the MEMS device is in the error state.
