Abstract
A semiconductor device according to the present invention comprises a first non-volatile memory, a second non-volatile memory in which initial data is stored, and an initialization controller for initializing the first non-volatile memory, wherein the second non-volatile memory has anti-stress properties higher than those of the first non-volatile memory, and the initialization controller reads the initial data from the second non-volatile memory when the first non-volatile memory is initialized and copies the read initial data in the first non-volatile memory to thereby initialize the first non-volatile memory.
