ABSTRACT:
A semiconductor device10sets a pass-through flag to ON when the top address of a write-prohibited area is passed. When a request to write data to a write-restricted area WRA is received, the semiconductor memory device10determines whether or not the pass-through flag is set to ON, and if the pass-through flag is not set to ON, the semiconductor memory device10executes writing of the data to the write-restricted area. On the other hand, if the pass-through flag is set to ON, the semiconductor memory device10does not execute writing of the data to the write-restricted area.
