Abstract
By inputting voltages to global word lines of a memory, and by detecting currents of corresponding global word lines, a relation function between the currents and the voltages can be generated, and connection defects on the global word lines can be determined according to various types of deviation of a relation curve corresponding to the relation function between the currents and voltages.
