摘要： PURPOSE:To enable a testing in a tester with a limited number of measuring terminals by connecting a plurality of output terminals of a semiconductor device in common to make a terminal to be measured enable while other terminals are made to disable to test. CONSTITUTION:For example, four output terminals O1-O4 are connected in common to form a first block. A common connection point of the output terminals is connected to a measuring terminal E1 of a tester 102. Moreover, enable/disable state of the terminals O1-O4 is controlled by control signals T1-T4 with a clocked inverter. The same is with those following a second block where terminals O5-O8 are connected in common. Then, when the signal T1 is turned to an H level and the signals T2-T4 at a L level, input data I1, I5... are applied to terminals E1, E2.... In such a manner, a function and electric characteristic of the terminals O1, O5... are tested and other output terminal are made high in impedance. The signals T2-T4 are turned to the H level sequentially and a test is performed in the same way thereby enabling the testing of all of the output terminals.
