Semiconductor devices providing test mode related to reliability

Abstract

A semiconductor device includes a pull-up source voltage generation circuit configured to drive a pull-up voltage to a normal voltage during a normal period and to drive the pull-source voltage to a test voltage during a test period. The semiconductor device also includes a pull-down source voltage generation circuit configured to drive a pull-down voltage to a ground voltage during the normal period and to drive the pull-down source voltage to a bit line pre-charge voltage during the test period. The semiconductor device further includes an equalization control signal driver configured to receive the pull-up source voltage and the pull-down source voltage to drive an equalization control signal for equalizing voltage levels of an internal bit line pair of a bit line sense amplifier.
