Abstract
A static memory cell is connected with word lines and data lines. First and second switches are connected in series between a data line and an output circuit. A sense amplifier has an input/output terminal connected to a common connection point of the said first and second switches. The first switch is turned off in synchronism with commencing operation of the sense amplifier such that the parasitic capacitance of the data line as viewed from the sense amplifier decreases. The second switching means is turned on a predetermined time later in order to transmit the output signal of the sense amplifier to the output circuit.
