    摘要: A semiconductor memory device wherein the equivalent series resistances that are interposed in series in the pairs of complementary data lines D, D, are substantially the same as one another among the individual complementary data lines D, D. The equivalent series resistance is comprised of pull-up MISFET's and column switching MISFET's that exist between the power source V.sub.CC and the sense circuit. Parity is maintained for the pull-up MISFET's (Q.sub.p, Q.sub.p) and the column switching MISFET's (Q.sub.y, Q.sub.y) that exist on the pairs of complementary data lines D, D. To maintain this parity, the two MISFET's are formed to have the same shape. In addition, the arrangement of contacts to the transistors are set so that the directions in which the currents flow and lengths of current paths are also the same. In other words, contact portions between aluminum electrode and source and drain regions are formed at the same positions in the two MISFET's.

    摘要: A memory device wherein a voltage dropped by a fixed voltage from a highest operating voltage is divided using a plurality of impedance elements, and common data lines are biased by the divided voltages. Owing to the application of the voltage dropped by the fixed voltage from the highest operating potential, even when resistance values of the impedance elements are reduced, a current to flow through the impedance element path does not increase considerably, and a low power consumption is attained. Owing to the reduced resistance values of the impedance elements, time constants which are determined by the resistances and stray capacitances parasitic to the common data lines are decreased. Thus, the potential changes of the common data lines to arise in correspondence with information stored in a memory cell are quickened, and a data sense time is curtailed, whereby an access time can be shortened.
