ABSTRACT:
An IC card having nonvolatile and volatile memory is disclosed. An IC card generates a volatile object, and accesses the volatile object using a reference address on a nonvolatile memory. These volatile objects are dynamically generated. The objects are allocated addresses in order from volatile objects with shorter terms to volatile objects with longer terms, so as to allow garbage collection and reuse of a volatile memory.
