ABSTRACT:
There is provided a nonvolatile semiconductor memory wherein a normal mode voltage is provided to a selected word line when a normal mode is selected, and a test mode voltage lower than the normal mode voltage is provided to the selected word line when a test mode is selected, thus leakage current is detected by selecting the test mode.
