An integrated circuit includes a normal data storage unit configured to store normal data and output the stored normal data in response to a write command, a read command, and an address signal in a normal operation mode, a test data storage unit configured to store the address signal as test data in response to the write command in a test operation mode, and output the stored test data in response to the read command, and a connection selection unit configured to selectively connect a data input/output terminal of the normal data storage unit or a data output terminal of the test data storage unit to a global line based on whether the integrated circuit is in a first or second one of the normal operation mode and the test operation mode, respectively. |
