According to one embodiment of the present invention, a method of operating an integrated circuit including a plurality of resistance changing memory cells grouped into physical memory units is provided. The method includes: Monitoring writing access numbers assigned to the physical memory units, each writing access number reflecting the number of writing accesses to the physical memory unit to which the writing access number is assigned; if the value of a writing access number assigned to a first physical memory unit exceeds a writing access threshold value, a data exchange process is carried out during which the data content stored within the first physical memory unit is exchanged with the data content of a second physical memory unit having a writing access number of a lower value. |
