Abstract: A system for supplying power to a volatile semiconductor memory having a memory array, with the semiconductor memory being provided with a standby voltage that is present at a second connection of the semiconductor memory. To implement the power supply system as simply and with as few components as possible, the semiconductor memory is provided with a stabilization circuit for stabilizing the standby voltage that has a low impedance when the input voltage is elevated and a high impedance when the input voltage is too low to supply the semiconductor memory.

Abstract: A system for supplying power to a volatile semiconductor memory (1) having a memory array (3), with the semiconductor memory (1) being provided with a standby voltage (V_STBY) that is present at a second connection (7) of the semiconductor memory (1). To implement the power supply system as simply and with as few components as possible, the semiconductor memory (1) is provided with a stabilization circuit (10) for stabilizing the standby voltage (V_STBY) that has a low impedance when the input voltage (V_STBY) is elevated and a high impedance when the input voltage (V_STBY) is too low to supply the semiconductor memory (1, 1a).

Abstract: A circuit arrangement for the interference-free evaluation of signals is disclosed, with which output signals of sensors can be evaluated; two inputs are needed for each sensor. If a ground-referred signal evaluation is to be done, then only one input is needed for each sensor. The evaluation is done using differential circuitry; in the operating mode with ground reference, the differential signal processing is done by employing an internally generated reference voltage. The choice of operating mode of the circuit arrangement can be made from outside freely via its own control pin.

Abstract: An electronic control unit having a housing, a substrate, particularly a hybrid, arranged in the housing and having an electronic control circuit. The electronic control unit also includes at least one device plug secured to the housing having contact elements that are electrically conductively connected to the control circuit of the substrate. A second substrate is arranged in the housing, spatially separated from the first substrate. At least one power component disposed in the housing and, electrically connected to the control circuit on the first substrate. One connecting printed circuit trace disposed in housing and conductively connected to the power component. The connecting printed circuit trace are conductively connected to a contact element, conducting power currents, of the device plug. Using the arrangement, in the event of a large number of contact elements in a device plug, the electrical connecting of the contact elements to the substrate can be simplified.
