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.
