ABSTRACT:
A semiconductor memory device having a plurality of pair cells including a pair of cells for storing ordinary data and auxiliary data in which the operation of one cell in a pair cell can be checked. At normal operation time data can be read from or written to a desired cell by activating two word lines at a time. On the other hand, at operation test time data can be read from or written to only one cell in a pair cell by activating a desired word line.
