Abstract
An improved burn-in voltage detection circuit for a semiconductor chip capable of detecting a predetermined voltage level related to a burn-in operation using a specific element irrespective of manufacturing variation, which includes an external voltage detection circuit for detecting whether an external voltage level is higher than a prescribed internal reference voltage level, and in response producing a burn-in enable signal; and a burn-in conversion detection circuit including a hysteresis characteristic, activated by the burn-in enable signal and responsive to the externally applied voltage and the internal reference voltage, for producing a burn-in signal of a first state as the external voltage is increased in magnitude above the level of the prescribed internal reference voltage by a component of the hysteresis characteristic, and a burn-in signal of a second state as the external voltage is reduced in magnitude below the level of the prescribed internal reference voltage by a component of the hysteresis characteristic.
