In a semiconductor memory circuit, when a memory cell is not selected, a pair of complementary data lines connected to the memory cell are short-circuited to be brought to the same potential, and when the memory cell is selected, the short-circuiting is cancelled. Therefore, the complementary data lines are in no way put in a floating condition, and when the memory cell is selected, a voltage difference corresponding to the data to be read out is immediately generated between the complementary data lines. Accordingly, the data is quickly fixed or settled, without being influenced by a preceding read-out data.
