PROBLEM TO BE SOLVED: To enable relieving a resistive defective cell without providing a spare cell as the most main feature. SOLUTION: For example, in a semiconductor memory device constituted so that such operation can be performed that sense amplifiers of (m) (m=1, 2, ..., n) pieces out of sense amplifiers of (n) pieces connected to the same data input/output line are accessed time sequentially and successively without specification from the outside of the device, the device is provided with a selecting circuit selecting in order sense amplifiers of (m) pieces out of sense amplifiers of (n) pieces and a switching circuit switching order of selection of the amplifiers of (m) pieces by this selecting circuit.
