Abstract: PURPOSE: A built-in self test circuit of a semiconductor device is provided which outputs the information regarding whether an error is occurred in a BIST(Built-In Self Test) circuit and the error detection of a tested circuit and the position of the circuit having an error through one output terminal. CONSTITUTION: A built-in self test circuit of a semiconductor device includes an ATPG(Automatic test pattern generator)(210), a comparison circuit part(220), a MISR(Multiple Input Signature Register)(230) and a position identifier(240). The ATPG outputs test patterns to test a DUT(Device Under Test)(100) to the DUT or to the comparison circuit part, and outputs test points showing the operation state of the ATPG itself to the MISR. The comparison circuit part compares the test patterns from the DUT with the test patterns from the ATPG, and outputs comparison signals and test points showing the operation state of the comparison circuit part itself. The MISR outputs compression signals by compress the test points from the ATPG and the comparison circuit part according to an algorism. The position identifier outputs serial test result signals. The BIST circuit detects the error of the DUT and the BIST with a row of test result signals during the test operation of the DUT. The circuit can reduce the size of the whole chip and the fabrication cost and can increase the production yield.
