    摘要： Disclosed is a semiconductor memory device includes two equalizing elements, each connected between a pair of bit lines and being separately subjected to on/off control by respective control signals. When performing a test, one of the control signals is kept HIGH and the other of the control signal is kept LOW during a precharge period, and activation/deactivation of the two equalizing elements is separately controlled. A failure such as a defect in one of the two equalizing elements subjected to the on/off control by the control signal can be thereby detected.
