Abstract
The present invention relates to a semiconductor memory device and more particularly to a power supply voltage detecting circuit of a semiconductor memory device which senses a voltage level of the power supply voltage. A power supply voltage detecting circuit of the present invention includes a circuit for generating a power supply voltage detecting signal by receiving a power supply voltage and a control circuit for generating a control signal in order to operate the circuit for generating the power supply voltage detecting signal when being in a specific mode state. The power supply voltage detecting circuit according to the present invention can reduce power consumption by cutting off a standby-current, since the power supply voltage detecting circuit is enabled during an activation of a chip. This allows the output signal of the power supply voltage detecting circuit to have an accurate voltage level of a power supply voltage or a ground voltage, so that chip operation speed can be improved and the effectiveness of the chip can be improved by removing noises.
