    摘要: A semiconductor device outputs data from a plurality of data nodes during a normal-operation mode, and outputs a test result from at least one of the data nodes during a test-operation mode. The semiconductor device includes a plurality of data-bus lines which convey the data with respect to the data nodes, and a data-bus switch which allows only the data-bus lines corresponding to the at least one of the data nodes to be driven in a first condition of the test-operation mode, and which allows all of the data-bus lines corresponding to the data nodes to be driven in a second condition of the test-operation mode.
