A memory cell including magnetic materials and heating materials, and methods of programming the memory cell are provided. A generation timing or a generation period of a control signal GC is decided in response to a lapsed time in operation of the receiver device. Further, a visual indication of results from each of the plurality of the predefined affine transforms is presented to the user and input is received from the user selecting one of the visual indications. The device makes it possible to achieve low energy consumption, an expanded controllability and greater operational safety in a simple manner.
