ABSTRACT:
A semiconductor memory device has a main word decoder for selecting a cluster from a memory cell block, and the main word decoder stores pieces of control data information each representative of whether the cluster is defective or non-defective; while an external device is sequentially accessing the clusters, the main word decoder skips the defective clusters on the basis of the piece of control data information, and accelerates the data access to the clusters.
