The method includes receiving a write request for a predetermined page; performing a write operation on a first log block that corresponds to a first data block including the page; receiving an update request for the page; and performing a write operation on a second log block that corresponds to the first data block. The memory card system includes: at least one non-volatile memory including a data block and a log block for updating the data block; and a memory controller controlling an operation of the non-volatile memory. During a write operation for a predetermined page, the controller controls writing of a first log block corresponding to a first data block including the predetermined page, and controls writing of a second log block during an update operation of the predetermined page.
