Abstract An apparatus comprising: a memory having at least two sections; a security element associated with at least one of said at least two sections; and a processor for controlling access to at least one of the at least two sections of the memory in dependence on a value of the security element. The apparatus may be an integrated circuit and the memory may be a read-only-memory storing generic code in one of the sections and code specific to a mobile communication device provider in the second section. The security element may be a permanently programmed memory element programmed by the IC manufacturer.
