Abstract
An improved semiconductor memory having a plurality of sense amplifier circuits corresponding to each bit line of a plurality of columns. A first common line is connected in common to the sense amplifier circuits, and a second common line is connected to the first common line. A first switching element is connected between the second common line and a reference voltage potential terminal, and a second switching element is connected to the first common line and the reference voltage potential. The second switching element corresponding to the first common line connected to one of the sense amplifier circuits is made conductive in response to a selection of the sense amplifier is disclosed.
