Abstract
An integrated circuit includes a control circuit, a one-time programmable circuit, and a security feature. The control circuit determines if the one-time programmable circuit is programmed in response to a request by a user of the integrated circuit to access the security feature. The control circuit generates a signal to indicate to the user of the integrated circuit that the security feature has been previously accessed if the control circuit determines that the one-time programmable circuit has been programmed to indicate a previous access to the security feature. The control circuit causes the one-time programmable circuit to be programmed in response to the request if the control circuit determines that the one-time programmable circuit has not been programmed.
