Abstract
A semiconductor memory apparatus includes an input buffering block configured to buffer an input signal transmitted from an input pin, a latch block configured to latch the input signal buffered by the input buffering block, a defect discriminating block configured to discriminate whether or not the input signal latched by the latch block is defective signal in response to a test mode signal, and a data output buffer configured to buffer an output signal of the defect discriminating block to transmit it to a data output pin, wherein the input signal is one of an input command signal and an input address signal.
