    摘要: An integrated semiconductor memory device includes memory cells each with a selection transistor and a storage capacitor. Memory cells of this type are usually read by the potential of the bit line to which the memory cell is connected being compared in a sense amplifier with the potential of a complementary, second bit line and a voltage difference identified being amplified. The semiconductor memory according to the invention provides for that capacitor electrode which is not connected to the selection transistor to be connected to the complementary, second bit line. As a result, for an operating voltage with the same magnitude, larger quantities of charge can be stored in the storage capacitor since now the two mutually spread potentials output by the sense amplifier are used for biasing the storage capacitor. The resultant increase in the signal strength makes the semiconductor memory insensitive toward signal corruptions which arise for example in the case of operating voltages at different levels for selection transistors and for transistors in the signal amplifier.

    摘要: Semiconductor memories (1) have segmented word lines (5a, 5b), which in each case have a main word line (10a, 10b) made of a conductive metal and a plurality of interconnect segments (15a, 15b) coupled to the main word line (10a, 10b), which are coupled to the respective main word line (10a, 10b) in each case via at least one contact hole filling (11). If one of the contact hole fillings (11) is defective or at high resistance then functional errors of the semiconductor memory occur. The interconnect segments (15a, 15b) of two respective word lines (5a, 5b) can be short-circuited in pairs with the aid of switching units (20), whereby a static current (I) that flows via the contact hole fillings (11) can be used for electrically stressing the contact hole fillings (11). Electrical stressing of contact hole fillings of segmented word lines is thus made possible.
