Abstract
A non-volatile semiconductor memory according to an embodiment includes: a data storage unit including a memory cell array and a writing circuit; an encoder that directs the writing circuit to write write data to the memory cell array; a writing determining circuit that determines whether the writing of the write data to the memory cell array within a predetermined number of writing operations fails or succeeds, inverts the write data to generate new write data when the writing of the write data fails, and directs the writing circuit to write the new write data to the memory cell array; a switching circuit that inverts read data which is read from the memory cell to generate new read data when the writing determining circuit determines that the writing of the write data fails; and a decoder that decodes the read data into the information data.
