Abstract
An integrated circuit can be made more secure by programming a one time programmable circuit so that different signals are provided on terminals as compared to when the integrated circuit was not secure. Instead, or in addition, the integrated circuit can be made more secure by providing decode circuitry that can be used with the one time programmable circuit to select different internal address maps in response to an address value. The decode circuitry can use a first address map when the integrated circuit is secure, and a different address map when the integrated circuit is non-secure.
