Abstract

A method is provided, including following operations: activating a first word line to couple a first bit line with a second bit line to form a first conductive loop through a first transistor having a first terminal coupled to the first bit line and a second transistor having a first terminal coupled to the second bit line, wherein second terminals of the first and second transistors are coupled together; activating a second word line to couple a third bit line with a fourth bit line to form a second conductive loop, wherein the first and second word lines are disposed below the first to fourth bit lines; and identifying that the first conductive loop, the second conductive loop, or the combinations thereof is short-circuited or open-circuited.
