Patent ID: 7117012

Claim:
A method for operating a data carrier equipped with a communication device, a memory device and a program execution unit for executing function programs contained in the memory device, comprising the steps: installing a function program in the memory device of the data carrier for realizing a loader interface which in turn makes it possible to reload function programs each realizing a load application, providing a free memory space available for the loader interface in the memory device, reloading at least one load application via the communication device into the memory device, said reloading being controlled by the loader interface, and the load application being allotted a part of the free memory space as an assigned address space; wherein the loader interface transfers the management of an assigned address space completely to a load application after the load application is assigned to the assigned address space, such that the loader interface has no further influence on or access to the assigned address space; and wherein the load application is configured to load at least one application program into said assigned address space.
