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.

Abstract: A circuit for generating an internal voltage to be supplied to memory elements of a semiconductor memory chip during normal operation and for providing an external voltage to the memory elements during a burn-in test operation. The circuit may be constructed with a driver circuit (50) which receives an external voltage and is controlled to generate the internal voltage. A comparator (300) compares the internal voltage to a first reference voltage to produce a control signal G2 to control the driver circuit (50). An external voltage detector (100) compares a second reference voltage to the external voltage to generate control signal B2. A driver control circuit (200) is enabled by control signal B2, if the external voltage is less than the second reference voltage, to pass control signal G2 to the driver circuit and thereby enable generation of the internal voltage to be equal to, or less than, the operating voltage of the semiconductor memory chip.
