<P>PROBLEM TO BE SOLVED: To provide a semiconductor storage system and a method of controlling the same by which errors of data can be corrected. <P>SOLUTION: A semiconductor storage system includes a memory region having a plurality of memory cells, and a memory controller having a data control unit in which when write-in is performed, after first-order ECC encoding is performed for input data, the first-ECC-encoded-result is compressed, control is performed so that input data can be written by performing second-order-ECC-encoding, and when reading is performed, data of the memory region is read and first-order-ECC-decoding is performed, after the first-order-ECC-decoded result is decompressed, second-order-ECC decoding is performed, control is performed so that data of the memory region is read. <P>COPYRIGHT: (C)2011,JPO&INPIT |
