    摘要: An internal voltage generation circuit including a drive control signal generator and an internal voltage driver. The drive control signal generator generates a drive control signal in response to an active pulse signal and a drive signal. The internal voltage driver, electrically coupled to the drive control signal generator, divides a level of an internal voltage signal in response to the drive control signal to generate a division voltage signal, compares a level of the division voltage signal with a level of a reference voltage signal to generate the drive signal, and drives the internal voltage signal in response to the drive signal.

    摘要: A test circuit of a semiconductor apparatus includes a test temperature information generation section, an erroneous operation prevention unit, and a refresh cycle adjustment unit. The test temperature information generation section outputs test temperature information having a plurality of bits in a test operation mode, and irregularly changes logic values of the plurality of bits and transition time points of the logic values. The erroneous operation prevention unit generates a temperature compensation signal in response to the test temperature information. The refresh cycle adjustment unit changes a cycle of a reference refresh signal in response to the temperature compensation signal, and generates a refresh signal.
