CHIP CARD WITH MEMORY FOR PROGRAMS WHICH CAN BE RELOADED AS A FUNCTION OF THE APPLICATION |
摘要 |
The invention relates to a chip card (CK) containing a program execution unit(P) and a memory (S) for at least one application dependent reloadable program(P1..Pn), whereby in each reloadable program (P1..Pn) first command statements(OP11..OP1z) with absolute address parameters (adr11..adr1z) which refer to a memory areas (S1) not occupied by the reloadable program (P1..Pn) are separated from second command statements (OP21..OP2x) with absolute address parameters (adr21..adr2x) which refer to the memory area (B1..Bn) occupied by the reloadable program (P1..Pn). One advantage of the invention is that the reloadable program can be reloaded at each random start address (SA..SAn) in the memory (S) in an application dependent manner and can be adapted to said address by the program execution unit (P). Another advantage provided by the invention is that the creation of different reloadable program versions relating to possible application conditional start addresses is no longer necessary.
