摘要：A non-volatile storage device comprises non-volatile memories for storing data;and a memory controller for carrying out control of the non-volatile memory. Thememory controller stores second error correcting code as well as first error correcting

code stored in the same page of the data. The memory controller, when writing datasmaller than a predefined size, does not add the second error correcting code, andstores duplexed data of the data and the first correcting code in a different page. Thememory controller, when reading, corrects data using the first and/or second correctingcode. The valid data management table manages which logical block stores valid datawith respect to an identical logical address.
