ABSTRACT:
The present invention discloses a circuit for detecting a negative word line voltage including a detecting unit for detecting a negative word line voltage in a detection node by using a plurality of loads coupled in series between a power supply terminal and a negative word line voltage terminal, a test signal generating unit for generating a plurality of test signals for detecting variations of the negative word line voltage, and a control unit driven according to the test signals, for controlling a potential of the detection node by adjusting a number of the loads of the detecting unit. The circuit for detecting the negative word line voltage can detect a wanted level of negative word line voltage by using the plurality of test signals without modifying the circuit, to reduce a development period of DRAM semiconductor products.
