Abstract
The memory card of the present invention includes an error correction circuit having an error correction code (ECC) computing circuit for computing the error correction codes, in blocks, for the data stored in a main memory, an ECC memory for storing the error correction codes computed by the ECC computing circuit, an ECC control circuit for comparing error correction codes computed for updated data with error correction codes previously computed for corresponding original data stored in the ECC memory, and for producing a signal indicating the result of the comparison, and an error correction controller for finding and correcting errors based on the result of the comparison produced by the ECC control circuit.
