ABSTRACT:
A semiconductor dynamic random access memory device is equipped with rows of redundant memory cells for replacing defective rows of regular memory cells therewith, and a redundant system associated with the rows of redundant memory cells is enabled in a test sequence for selectively energizing redundant word lines in response to external address signals so as to eliminate an address pointer only used in the test sequence.
