PROBLEM TO BE SOLVED: To provide an integrated circuit that can censor access to memory regions.SOLUTION: An integrated circuit includes a non-volatile memory module that can censor access to various memory regions on the basis of censorship criteria. Information used to implement the censorship criteria is stored at a non-volatile memory location. A one-time programmable non-volatile memory location stores a value representing a permanent censorship key. If the permanent censorship key is in an erased state, one or more resources are allowed to modify the non-volatile memory location and disable censorship. If the permanent censorship key has one or more programmed bits, no resource is allowed to modify the non-volatile memory location and disable censorship. |
