<p>PROBLEM TO BE SOLVED: To make it possible to control reading of data which one wants to make confident in an integrated circuit which can have a specified protocol read the data to outside. SOLUTION: An integrated circuit where data stored in a memory 107 is read by supplying control data using an access port 101 is equipped with an access detection means 111 for detecting that there is an access which uses the access port 101, and an output prohibition means 120 which prohibits prescribed data stored in the memory 107 from being outputted when this access detection means 111 detects the access.</p> |
