ABSTRACT:
A memory structure with a repair function and a repairing method thereof are provided. The memory structure has an independent main memory unit and register file design. It also incorporates a record control unit for storing the fault information of the main memory unit. Upon receiving an access command, the memory structure determines if the main memory space pointed by the access command is faulty according to the stored fault information. When the main memory space pointed by the access command is faulty, a backup memory space is selected from the register file to replace the faulty main memory space. Therefore, the present invention can provide the convenience of a modularized design and reduce the space occupation of the register file, and also improve the access efficiency of the memory.
