Abstract
A semiconductor apparatus includes an input buffer configured to buffer and output data inputted from a data input/output pad; a data input control unit configured to transfer data outputted from the input buffer; a data output control unit configured to transfer inputted data to an output buffer; the output buffer configured to buffer data outputted from the data output control unit, and output the buffered data to the data input/output pad; a test data input/output unit configured to latch test inputted data inputted and output test latch data or latch an output of the input buffer and output the test latch data; and a test loop control unit configured to transfer data or the test latch data to the data output control unit.
