Abstract
Method for detecting word line defect includes activating a first word line for reading a first data pre-stored in the memory cell, suspending the first word line for a predetermined period and then writing a second data complementary to the first data into the memory cell, activating again the first word line for reading a third data from the memory cell, and comparing the second and the third data for determining if an electrical coupling path exists between the first word line and a second word line.
