Abstract
An integrated circuit package which has a flexible circuit that covers an integrated circuit. The flexible circuit contains a conductive line which prevents a probe from accessing the integrated circuit. The conductive line of the flexible circuit can be attached to the power lines, synchronization line, memory erase line, or any other line that will disable, erase or otherwise prevent access to the integrated circuit if the flexible circuit conductive line is broken. The integrated circuit can be mounted to a printed circuit board. The printed circuit board, integrated circuit and flexible circuit can all be enclosed within the package.

A method comprising:
- providing a flexible circuit including a conductive line;
- coupling the conductive line to a protected integrated circuit;
- routing the conductive line to a synchronous clocking signal of the protected integrated circuit only, the synchronous clocking signal providing a valid synchronous signal to the protected integrated circuit;
- placing the flexible circuit on the protected integrated circuit to cover at least a top surface of the protected integrated circuit;
- and
- disabling the protected integrated circuit by preventing the protected integrated circuit from receiving the synchronous clocking signal if the conductive line of the flexible circuit is broken.
