    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.

    摘要: An integrated semiconductor memory device includes a memory cell array (B1) with a first bit line and a second bit line (BL, /BL), a controllable resistor (SW) and a control unit (100) configured to control the controllable resistor. In a first operating state of the integrated semiconductor memory device, the first and second bit lines are connected to one another via a first controllable switch (ET1) and also via the controllable resistor (SW) which has been set to a low resistance, to a connection (A10) that applies a mid-voltage (VBLEQ), where the voltage level of the mid-voltage is in the form of an arithmetic mean between a first and second voltage potential (VBLH, VBLL). By virtue of the control unit briefly setting the controllable resistor to a very low resistance in the first operating state of the integrated semiconductor memory device, the period of time required for the first and second bit lines require to assume the mid-voltage (VBLEQ) is shortened. The influence of capacitive coupling influences, which slow down the charging of the first and second bit lines to the mid-voltage, is significantly reduced as a result.

    摘要: An integrated semiconductor memory includes at least one word line and a number of memory cells. Each memory cell has a selection transistor coupled to the word line. A word line driver is coupled to the word line. The word line driver provides a first electrical potential or a second electrical potential to the word line such that the word line is activated by the first electrical potential and is deactivated by the second electrical potential. A passive component (e.g., a diode or a resistor) is coupled between the word line and the second electrical potential such that the word line is coupled to the second electrical potential in a high-resistance fashion through the passive component. The passive component is transmissive for a leakage current between the word line and the contact connection.

    摘要: An integrated circuit includes an input terminal (IN) for application of a supply voltage (Vext) and an output terminal (A) for generation of an output voltage (Vout). A first branch including a first controllable resistance (T1) and a second branch including a charge pump (10) and a second controllable resistance (T2) are connected between the input terminal (IN) and the output terminal (A). A control circuit (20) alters the resistance values of the first and second controllable resistances (T1, T2) in a manner dependent on a ratio of an actual value (Vout) of the output voltage to a desired value (VSout) of the output voltage and a ratio of an actual value (Vext) of the supply voltage to a desired value (VSext) of the supply voltage. As a result, the output voltage (Vout) can be stabilized to the desired value (VSout) virtually independently of fluctuations of the supply voltage.
