  • Patent number: 9817711
    Abstract: An ECC circuit can operate in a plurality of error correction modes with different correcting capabilities for data stored in a memory. The ECC circuit calculates a syndrome with respect to information data in accordance with an error correction mode set by a control part and adds a syndrome of a fixed length in which dummy bits are added to the calculated syndrome, to the information data. When code data is read out, the ECC circuit performs a correction process on the code data by using the syndrome included in the code data.
    Type: Grant
    Filed: September 5, 2014
    Date of Patent: November 14, 2017
    Assignee: MegaChips Corporation
