Abstract
There is to provide a semiconductor device capable of realizing a start time diagnosis on a non-volatile memory without any external device and any non-volatile memory out of a diagnosis target. The non-volatile memory includes an address space formed by addresses continuously read and a reservation address formed by a single or a plurality of addresses, read after the address space. A previously calculated value fixed data is stored in the reservation address. When all the data stored in the address space and the value fixed data are compressed using a predetermined initial value according to a predetermined compression algorithm, the value fixed data is the data for converging the compression value to a predetermined fixed value (for example, 0).
