Abstract
A voltage monitor is provided. The voltage monitor includes a voltage divider, a bridge switch and an off-chip driver (OCD). The voltage divider receives an internal voltage in the memory device, and divides the internal voltage to generate a sensing voltage on a sensing node. The bridge switch is coupled between the sensing node and a connecting pad. The OCD includes a control switch, a pull-up switch and a pull-down switch. A first terminal of the control switch is coupled to a high reference voltage. The pull-up switch is coupled between a second terminal of the control switch and the connecting pad. The pull-down switch is coupled between the connecting pad and a low reference voltage. The bridge switch is turned on in a test mode. The control switch, the pull-up switch and the pull-down switch are turned off in the test mode.
