Abstract
A first device includes a processor, a first memory, and a memory manager. A second device includes a second memory and a first application program, and a third device includes a third memory and a second application program. The first application program is loaded into the first memory to be executed by the processor. Application program variables related to the first application are stored in the first memory. The second application program to be executed by the processor is loaded into the memory in at least a partially overlapping manner of the first application program. The creation of second application program variables related to the second application program in the first memory is in a region not occupied by the first application program. Alternatively, the first and second application programs may be in the same device and/or memory.
