PROBLEM TO BE SOLVED: To simplify a circuit configuration in the case of initializing a memory. SOLUTION: An address control section 113 sets a read address in a head address =000, sets a write enable signal to a low level for a period before a cycle of a read address, and sets the signal to a high (active) level for a period after the cycle. A read section 111 reads data from an area pointed out by the read address for a period when the write enable signal is at a low level, then an initializing section 112 writes initialized data (e.g. FF) to an area pointed out by the read address for a period when the write enable signal is at a high level and this continues up to a final address = FFF even when no user information is stored.
