PROBLEM TO BE SOLVED: To make it possible to hide a memory fault for improved memory reliability by a simplified configuration.SOLUTION: A memory access control device 30 comprises: a replacement information storage unit 31 for storing, in memory 20 comprising a plurality of bits, bit replacement information 310 which associates an identifier to identify logically fixed bits of which values are logically fixed and an identifier to identify a fault bit of which value is fixed by a fault to a value indicated by the logically fixed bits; and an access control unit 32 for processing accesses to the memory 20 after replacing the logically fixed bits and the fault bit on the basis of the bit replacement information 310.
