ABSTRACT:
An improved burn-in sensing circuit for a semiconductor device generates a signal for indicating a start of a burn-in mode when an external voltage exceeds a predetermined level of a logic threshold voltage. The circuit obtains a desired hysteresis characteristic between a burn-in entry voltage and a burn-in exit voltage by lowering a level of the logic threshold voltage, and includes an external voltage sensor for dropping and outputting an external voltage in accordance with a bias voltage applied thereto. A burn-in signal generator of the circuit generates a predetermined level of a burn-in signal, and feeds back the predetermined level of a burn-in signal to lower the logic threshold voltage when a predetermined level of dropped voltage is higher than its logic threshold voltage.
