A semiconductor memory device includes a first memory cell block capable of rewriting data and having at least one first memory cell, and a second memory cell block capable of rewriting data and having at least one second memory cell adjoining the first memory cell. A data writing method for the semiconductor memory device includes writing data into the first memory cell, writing data into the second memory cell following writing the data into the first memory cell, verifying the data of the first memory cell after writing the data into the second memory cell, and rewriting the data into the first memory cell when insufficiency of the data of the first memory cell as a result of verifying the data of the first memory cell.
