    Abstract: A method for determining resistances at a plurality of interconnected resistors in an integrated circuit and a resistor configuration in which the resistors are interconnected to form a ring structure. Two measurement pads are in each case provided at the nodes between two resistors. The measurement pads can be used for feeding in current and for measuring voltage according to the known four-point measurement method. The effect of the ring structure is that fewer measurement pads are required, in contrast to the customary series circuit of resistors. By way of example, in the case of a ring structure with four resistors, two measurement pads are advantageously saved. The consequently reduced chip area required for the ring structure is advantageous particularly in the case of test circuits, which can be arranged for example in the narrow sawing frame between two chips.

    Abstract: The measuring probe has a lever arm provided with a probe point at its free end and made of a high conductivity material (14), e.g. doped crystalline silicon, covered by an extremely thin insulation layer (15), e.g. of silicon oxide, with a window (16) in the insulation layer at the apex of the probe point. The lever arm is contacted via a metal layer (17) applied over an opening in the insulation layer. Also included are Independent claims for the following: (a) a manufacturing method for a measuring probe; (b) a measuring system using a measuring probe

    Abstract: A ring oscillator has a multiplicity of inverters. An interconnect is connected between two of the inverters, and a storage capacitor to be measured, with its associated lead resistor, is coupled to the interconnect either via an interconnect or a transistor can selectively coupled and decouple the capacitor and the lead resistance. A measuring device is connected up to the ring oscillator and is used to determine a value for the oscillation frequency of the ring oscillator on the basis of which a value for the time constant of the storage capacitor can be determined.

    Abstract: An integrated dynamic memory includes a memory cell array having memory cells each assigned to one of a plurality of groups. The plurality of groups are divided into defect-free groups having exclusively defect-free memory cells and into defective groups having at least one defective memory cell. The memory further includes a memory configuration table that contains a list of the defect-free groups and an assignment unit that, based upon the entries in the memory configuration table, executes memory accesses only to those memory cells assigned to a defect-free group. The total capacity of the memory module, then, is not fixed once and for all with fabrication, but, rather, results only after a memory test, or may even vary in the course of the module lifetime.
