ABSTRACT:
An internal power voltage generating circuit of a semiconductor memory device may be constructed with a voltage sensing circuit (100) and a reference voltage controller (300) providing an internal power voltage int. V.sub.CC of a given reference voltage amplitude V.sub.ref and an external power voltage amplitude ext. V.sub.CC. Thus, when a high voltage over an operating voltage of a chip is applied to a pad (10) of the chip, the internal power voltage is raised to the level of the external power voltage. Therefore, when stress is added to the chip during a "burn-in-test", the defective chip is easily detected. Consequently, the reliability of those semiconductor memory devices subjected to post-manufacturing testing can be improved.
