PURPOSE:To obtain an inexpensive device capable of outputting a value which is not especially troubled in a normal using state by providing the device with an output selecting part for selectively outputting either one of the 1st data and compensating data as the 2nd data based upon a compared output. CONSTITUTION:This memory control device for comparing the 1st data read out from a non-volatile memory 2 with reference data by a memory control circuit 1 and outputting the 2nd data is constituted of a memory data judging circuit 1b for comparing the 1st data with the data of a reference data storing part 1c, an initializing value storing part 1d for generating compensating data different from the reference data and the output selecting part for selectively outputting the 1st data or the compensating data. Even when the contents of the memory are turned to an abnormal value, a value which is not especially troubled in a normal using state can be outputted and data capable of always attaining normal operation can be outputted. |
