ABSTRACT:
A semiconductor device is provided which comprises a memory mat formed by dividing a memory into a plurality of blocks and a circuit arrangement disposed at every memory mat block for generating access suppression signals at least for defective memory cells within that block. Using this arrangement, the access speed to a redundant memory cell array for relieving the defects is increased so that a semiconductor memory device capable of a high speed operation is obtained.
