ABSTRACT:
A memory card includes an error-correction-code (ECC) controller for generating ECCs, an ECC memory for storing ECCs generated by the ECC controller and an address converter for converting between addresses of the ECC memory and those of a main memory for storing data. The ECC controller generates an ECC to be stored in the ECC memory when a control data is input and the address converter fetches a relationship between an address of the ECC memory at which the generated ECC is stored and that of the main memory at which the control data is stored. Upon reading data stored in the main memory, error check and error correction operations are executed for the control data.
