Abstract
A semiconductor memory device includes a test address generating circuit configured on the device. The test address generating circuit generates a plurality of test addresses for a test of the semiconductor memory device in response to at least one externally applied test address generation signal. As a result, the number of DUTs can increase, based on a reduction of required address pins, and manufacturing productivity and test efficiency of semiconductor memory devices can increase.
