This disclosure concerns a memory including: word lines extending to a first direction; bit lines extending to a second direction crossing the first direction; a memory cell array including cell blocks each including memory cells respectively provided corresponding to intersection points of the word lines and the bit lines; and sense amplifiers provided corresponding to the bit lines, wherein the sense amplifiers copies existing data stored in a first cell block within the memory cell array to a plurality of memory cells, the memory cells being included in second and third cell blocks different from the first cell block, and alternately arranged in an extension direction of the word lines and also alternately arranged in an extension direction of the bit lines, and the sense amplifiers reads data from the second cell block or the third cell block, at a time of outputting data to outside of the sense amplifiers.
