A method of testing a semiconductor memory apparatus is provided. The data alignment units other than the one data align unit being tested are deactivated. Serial data is input to the activated data alignment unit to generate parallel data. The parallel data is decoded. A test mode signal corresponding to the decoded result is enabled to perform the test. Different serial data is input where the test mode signal is enabled to generate and decode parallel data. Both tests are then performed simultaneously based on a test mode signal corresponding to a result of the decoded parallel data.
