A vehicular memory management apparatus (1) includes in an SRAM (12) a mirror area for mirroring information from a PDTC storage area and an update information storage area for storing update information of the SRAM (12). When a fault is detected, a DTC is stored in both of the mirror area and a DTC storage area for maintaining consistency between the contents of the two areas, and the update information is updated. After confirming the consistency based on the update information, the information in the mirror area is copied to the PDTC storage area. Further, the information in the PDTC storage area is copied to the mirror area upon determining that the information in the mirror area is deleted based on the update information.
