Abstract:
A semiconductor memory device in accordance with the present invention is able to facilitate detecting whether a word line fails or not by floating the word line. The semiconductor memory device includes a word line driver, and a floating controller. The word line driver is configured to control a word line to be enabled/disabled. The floating controller is configured to control the word line driver to float the word line in response to a word line floating signal.
