ERROR CORRECTING LSI DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an error correcting LSI device which decreases its buffer size without losing conventional data processing capacity and capable of reducing the load on a system controller. SOLUTION: When an ECC block/time buffer management control part 113 for managing a buffer in each time and ECC block units judges that the error correction of an ECC block and data transfer processing of the ECC block to an external device can't be executed within the buffering time of the ECC block, a sector unit buffer management control part 114 for managing the buffer in each sector continues processing until a buffering processing pointer overtakes a data transfer processing pointer at a selector level.
