Abstract
A potential setting circuit is connected with a pair of common data lines which are made operative to receive data signals from memory cells. The potentials at the paired common data lines, which are forcibly set by the potential setting circuit, are set substantially at the middle level between the high and low levels of the data signals which are generated from the memory cells. As a result, the potential at the paired common data lines are changed within a relatively short time to the level of the data signals generated from the memory cells.
