Abstract

A device and corresponding operational method for storing frequency values to a memory of the device, comprising an internal memory and an external memory, are provided. A frequency value in a memory cell of the internal memory is actualized by an increment or a decrement. After a specific number of increments and decrements in the memory cells of the internal memory, a maximum frequency value of the frequency values stored in the memory cells of the internal memory is determined, and the maximum frequency value is transferred to a corresponding memory cell of the external memory. The memory cell of the internal memory that contains the transferred maximum frequency value is reset. After a period, content of each memory cell of the internal and external memory is read, and each memory cell of the internal and external memory is reset.
