1. A semiconductor memory device comprising:

  • a plurality of semiconductor memory cells;

    at least one word line coupled to said plurality of semiconductor memory cells for selectively transmitting an access signal thereto;

    at least one pair of data lines coupled to said plurality of semiconductor memory cells for transferring data with respect thereto;

    sense amplifier means coupled to said at least one pair of data lines for amplifying a data signal transferred therethrough;

    a dummy word line having a signal transfer property corresponding to that of said at least one word line;

    a dummy selection signal generating means coupled to said dummy word line for supplying a dummy selection signal to said dummy word line every time an addressing operation is effected; and

    energizing signal generating means coupled to said dummy word line for generating a first energizing signal for a preset period of time in each operation cycle to activate said sense amplifier means in response to a dummy selection signal transmitted through said dummy word line.
