发明名称 Easily testable semiconductor LSI device
摘要 In a large scale integrated (LSI) circuit, a through-passage circuit together with a selector circuit is provided between an input circuit and an output circuit, thereby enabling to selectively short-circuit the input circuit to the output circuit. In testing a complex circuit including two or more such LSIs, the internal circuit of the LSIs can be selectively extremely simplified to enable easy and fast testing.
