Abstract
A semiconductor memory device includes a plurality of memory areas. Each of the memory areas includes a normal cell array and a redundancy cell array for repairing defective cells generated in the normal cell array such that the semiconductor memory device is usable even when memory arrays include defective cells. A size of a redundancy cell array of a first memory area is greater than a size of the redundancy cell arrays of the other memory areas.
