    • By setting full group reversal control gates to a logical voltage "H", memory cells on all bit lines of a memory cell array block are connected to a reversal voltage supply circuit so that a group reversal operation is performed. When one of the group reversal control gates is set to the logical voltage "H", the memory cells on the bit lines having either even or odd numbers of the memory cell array block are connected to the reversal voltage supply circuit so that a partial group reversal operation is performed. When one of column selection gates is set to the logical voltage "H", the selected bit line is connected to the reversal voltage supply circuit. Consequently, a line reversal operation for the memory cell connected to the selected bit line is performed. Thus, the high-speed reversal operation which fully controls the offleak current of the memory cell can be implemented and the low-voltage operation can be realized by changing the operation unit for performing the reversal operation.

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

    • The memory controller writes and reads data in and from a nonvolatile memory. The nonvolatile memory has a plurality of memory cell blocks, each memory cell block includes a plurality of multi-level cells each capable of storing m-bit data (m is a natural number of two or more), a first page to a m-th page are allocated to the respective m bits of the multi-level cell, the memory controller sequentially writes the data to the memory cells from the first page in ascending order, and comprises a backup unit, and when a write command is received from the outside of the memory controller, in a case where a data write destination of the data in the nonvolatile memory is a n-th (n is a natural number of two to m) page of the multi-level cell, and data is already written in the first to (n-1)th pages, the backup unit copies the already written data to a nonvolatile storable backup region.

    • A source block (B0) and the logical page number (“8”) of a write target page are identified from the logical address of the write target page. Data objects (DN8, DN9, . . . , DN12) to be written, which a host stores in a page buffer (2), are written into the data areas (DA) of the pages (Q0, Q1, . . . , Q4) of a destination block (Bn), starting from the top page (Q0) in sequence. The logical page number (“8”) of the write target page is written into the redundant area (RA) of the top page (Q0). The physical page number (“6=8−2”) of the write target page is identified, based on the logical page number (“8”) of the write target page and the page offset (“2”) of the source block (B0). When notified by the host of the end of the sending of the data objects (DN8, . . . , DN12), the data items (D13, . . . , D31, D0, D1, . . . , D7) in the source block (B0) are transferred to the pages (Q5, Q6, . . . , Q31) in the destination block (Bn) via the page buffer (2) sequentially and cyclically, starting from the page (P11) situated cyclically behind the write target page (P6) by the number (“5”) of pages of the data objects (DN8, . . . , DN12).
