    Abstract: A semiconductor memory apparatus according to the embodiment includes a test mode controller, a first data alignment unit, a decoder, a test executing unit and a second data alignment unit. The test mode controller is configured to generate test enable signals in response to a test mode setting signal and a read command. The first data alignment unit is configured to parallely align first input data that are input in series, generate first alignment data, and transmit it to the first data driver. The decoder is configured to decode the first alignment data in response to the test enable signal and generate the decoding signal. The test executing unit is configured to execute the preset test mode in response to the decoding signal. The second data alignment unit is configured to parallely align second input data, which are input in series, in response to the test enable signal, generate second alignment data, and transmit it to a second data driver.
