In an integrated circuit in which data can be read out from a memory (107) by supplying control data through an access port (101), this integrated circuit includes an access detecting circuit (111) for detecting an access using the access port (101) and an output inhibit circuit (120) for inhibiting the output of data from the memory (107) when this access detecting circuit 111 detects the access. Therefore, in the integrated circuit in which data can be read out from the memory (107) outside of the integrated circuit by a standardized protocol, the reading of data that should be made unintelligible can be limited.
