    摘要: A current driver configuration for MRAMs includes word-line drivers and bit-line drivers at respective first ends of word lines and bit lines. The word line drivers and the bit line drivers each include a series circuit formed by an n-channel field-effect transistor and a current source. Further series circuits are provided at the respective second ends of the word lines and the bit lines. Each of the further series circuits includes a second n-channel field-effect transistor and a voltage source.

    摘要: A CMOS voltage divider having a first chain containing series-connected MOS transistors of a first conductivity type is described. Each of the MOS transistors have identical geometrical dimensions and, at the same time, each have identical gate-source voltages. The MOS transistors operate in the linear range of their characteristic curve and between opposite ends of the first chain an input voltage to be divided is present and at whose source terminals the voltage fractions can in each case be picked off. Provision is made of a second chain containing series-connected MOS transistors, complementary to the first MOS transistors. The second chain has the same number of transistors as the first MOS transistors and with the same geometrical dimension in each case. The MOS transistors of the first chain are connected to the MOS transistors of the second chain in such a way that each MOS transistor chain generates the gate-source bias voltage for the respective other MOS transistor chain.

    摘要: An integrated semiconductor memory has memory cells that are combined to form addressable normal units and to form at least one redundant unit for replacing one of the normal units. In addition, the semiconductor memory has an address bus to which an address can be applied, and a redundancy circuit that is connected to the address bus. The redundancy circuit is used to select the redundant unit. An input of a processing unit is connected to a connection of the address bus and also to a connection for a test signal, and the output of the processing unit is connected to an input of the redundancy circuit. The redundant unit can be tested before the repair information is programmed in the redundancy circuit. The circuit complexity required for this is comparatively low.

    摘要: A magneto-resistive random access memory (MRAM) configuration is described in which line driver circuits are respectively assigned via connecting nodes to two memory cell arrays, with the result that the area for the driver circuits can practically be halved. Therefore a space-saving architecture and a more efficient MRAM configuration is obtained.
