    Abstract: The device has a variable periodic refresh input signal receiver, a comparator (22) for comparing the period of the refresh input signal (14) with a defined value, an output device (22) for outputting a refresh output signal (24) depending on the comparison and a reset signal (26). A maximum or minimum period signal is output if the period is above a maximum or below a minimum value respectively, otherwise a proportional period signal is output. AN Independent claim is also included for a method of outputting a refresh signal for a memory cell of a semiconducting memory device.

    Abstract: The device has a capacitor, a differential current source for providing a capacitor charging current with temperature dependent and temperature independent current sources connected together so the current level of the capacitor charging current is proportional to the difference between the temperature dependent and temperature independent currents. A comparator outputs a refresh signal if the capacitor voltage exceeds a reference voltage. The device has a capacitor (C), a differential current source (14) for providing a capacitor charging current for charging the capacitor with temperature dependent and temperature independent current sources that are connected together so that the current level of the capacitor charging current is proportional to the difference between the temperature dependent and temperature independent currents. A comparator (12) outputs a refresh signal if the capacitor voltage (VC) exceeds a reference voltage (VREF). AN Independent claim is also included for the following: an arrangement for implementing the inventive method of producing a refresh signal for a memory cell of a semiconducting memory device, preferably a DRAM memory.

    Abstract: A method for increasing the external supply voltage (Vext) of an integrated circuit, using a two-stage charge pump (A,B) to transform the external supply voltage (Vext) on to a higher internal working voltage (Vpp). Two two-stage pumps (A,B) work in parallel in one multi-phase drive, where in a cyclic sequence the two pumps (A,B) work on a common first stage. An Independent claim is given for an integrated circuit.

    Abstract: The circuit has a control stage that produces a deactivation control signal in response to a deactivation command to set a controllable connection device in the conducting state. A selectively switched reducing device limits the current flowing via the conducting connecting device in the on state so that the total current flowing in a common line system providing a deactivation potential does not exceed a defined value. The circuit has a control stage (2) that produces a deactivation control signal in response to a deactivation command to set a controllable connection device (T2), which is provided for each word line (WL) for connecting it to a common line system (DL) for providing a deactivation potential, in the conducting state. A selectively switched reducing device (T7-T9, HL) limits the current flowing via the conducting connecting device in the on state so that the total current flowing in the common line system does not exceed a defined value.
