<P>PROBLEM TO BE SOLVED: To more efficiently perform smoothing for succession from processing for calculating a syndrome to processing for deriving an error position polynomial; and processing for deriving the error position polynomial, in a memory controller including a decryption circuit. <P>SOLUTION: Mutual correspondence of a region in a data holding circuit, a region in a syndrome holding circuit, and a region in a coefficient holding circuit is defined. A syndrome calculated based on data held in a first region in the data holding circuit is held in a second region serving as a region in the syndrome holding circuit that corresponds to the first region. A coefficient calculated based on the syndrome held in the second region is held in a third region serving as a region in the coefficient holding circuit that corresponds to the second region. A bit error of the data held in the first region is corrected based on the coefficient held in the third region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
