Abstract
Memory cells and a sense amplifier are connected to a pair of bit lines. Two dummy word lines are capacitively coupled with the pair of bit lines. One of the dummy word lines is driven to a high level before the sense amplifier starts the sense operation, and the other dummy word line is driven to a high level after the sense amplifier has started the sense operation. When the sense amplifier has terminated the sense operation, the two dummy word lines are driven to a low level.
