Abstract
A sense amplifier comprising a flip-flop circuit is provided for each bit line pair. A first transistor is connected between the flip-flop circuit and V.sub.DD power source. A second transistor is connected between the flip-flop circuit and ground. A control signal for controlling the active state of the flip-flop is applied to the gate of the first transistor, with a minimum time delay. The control signal is also applied to the gate of the second transistor, with a time delay corresponding to that caused by the word line. The timing for rendering each flip-flop circuit in the active state is substantially coincident with the optimum timing of a change in potential on each corresponding bit line.
