Abstract
A word line defect detection circuit configured to detect a defect of at least one word line selected from a plurality of word lines of a memory device includes a current generating circuit configured to generate a detection reference current having a first magnitude and to apply the detection reference current to the selected word line, and a sensing amplifier configured to measure a voltage of the selected word line generated based on the detection reference current. The word line defect detection circuit may be configured to detect a defect of the selected word line in response to the voltage of the selected word line having a value less than a first reference voltage.
