ABSTRACT:
At the time of burn-in test, substrate voltages of transistors in a sense amplifier are switched by a PMOS substrate voltage generating portion and an NMOS substrate voltage generating portion. Specifically, the substrate voltage of a P channel MOS transistor is increased during the test than in a normal operation, whereas the substrate voltage of an N channel MOS transistor is decreased during the test than in the normal operation. Consequently, the threshold voltages of the P channel and N channel MOS transistors can be increased upon the test. Leakage currents in the turned-off states can be reduced, and thus, power consumption during the burn-in test can be decreased.
