Abstract:
An integrated circuit device that utilizes multiple OTP bits to enable and re-enable access to evaluation and testing components comprises a set of multiple one-time programmable (OTP) bits, a programming module operable to trigger a change in each bit of the set of multiple OTP bits, decode logic to determine a value for a collective state of the set of multiple OTP bits, and a control element to control access to at least one resource of the integrated circuit device based on a value of the collective state for the set of multiple OTP bits.
