    摘要: A method for detecting a leakage current in a bit line of a semiconductor memory is disclosed. In one embodiment, the method includes isolating the connection of a sense amplifier from a bit line via an isolation transistor, reading out a memory cell to the bit line, waiting until a predetermined delay time has elapsed, so that a leakage current measurably changes the voltage on the bit line within the delay time. The sense amplifier is short circuited with the bit line via the isolation transistor. The voltage on the bit line is collected by the sense amplifier, and compared with a reference voltage so as to detect the leakage current.

    摘要: A semiconductor memory and a test method for testing whether word line segments (12) are floating after an activation operation or a deactivation operation is disclosed. For this purpose, the charge-reversal current (I) that occurs in the event of a word line segment (12) being subjected to charge reversal or a charge quantity (Q) which is fed to the word line (12) or conducted away from the word line segment (12) as a result of this is measured. If, upon activation or deactivation of a word line segment (12), the measured charge-reversal current (I) or the corresponding charge quantity (Q) is less than a lower limit value, it is ascertained that the relevant word line segment (12) has a defective contact terminal. In this way, high-impedance or defective contact hole fillings can thereby be identified and the associated word line segments (12) can be replaced by redundant word lines.
