Abstract
A bonding quality test circuit includes a switching circuit configured to provide a connection between a sensing node and a bonding node, the bonding node corresponding to a first end of a bonding resistor that is between a line provided to a memory device and a peripheral circuit, a precharging circuit configured to provide a precharge voltage to the line and the sensing node when the precharging circuit is connected to the line and the sensing node by the switching circuit, a latch circuit that includes a first node configured to provide a control output signal to the precharging circuit and a second node configured to have a voltage that is phase inverted with respect to a voltage of the control output signal, and a first transistor configured to provide an output signal according to the sensing node when the first transistor is connected to the second node.
