    Abstract: A system and method for testing a memory device is disclosed. One embodiment includes a plurality of memory cells. Each of the memory cells can be controlled by an address. A test memory for storing test results is provided. An address comparing unit is configured to determine whether the address of a memory cell lies in a predetermined address space. A controllable unit for storing test results is connected with the test memory and the address comparing unit. The controllable unit is controlled by the address comparing unit such that error information of the tested memory cell is only stored in the test memory if the address of the tested memory cell lies in the selected address space.

    Abstract: The device (100) includes a reference signal port (203) connected to a signal blocking unit (102) for blocking unwanted signals and to ensure that only a predetermined reference signal (204) is supplied to the electronic switching units (101a-101c). A power supply port (201) applies supply voltage (202) to the electronic switching units. An input signal port (205) supplies an input signal (206) to the electronic switching units. An output signal port (207) is provided to output an output signal (208) after supplying input signal and reference signal to the electronic switching units. An independent claim is included for the initialization process of the electronic switching device.

    Abstract: An integrated circuit includes an input terminal (IN) for application of a supply voltage (Vext) and an output terminal (A) for generation of an output voltage (Vout). A first branch including a first controllable resistance (T 1 ) and a second branch including a charge pump ( 10 ) and a second controllable resistance (T 2 ) are connected between the input terminal (IN) and the output terminal (A). A control circuit ( 20 ) alters the resistance values of the first and second controllable resistances (T 1 , T 2 ) in a manner dependent on a ratio of an actual value (Vout) of the output voltage to a desired value (VSout) of the output voltage and a ratio of an actual value (Vext) of the supply voltage to a desired value (VSext) of the supply voltage. As a result, the output voltage (Vout) can be stabilized to the desired value (VSout) virtually independently of fluctuations of the supply voltage.

    Abstract: An integrated circuit includes a current generator circuit with a first input terminal for applying a reference voltage and a second input terminal for applying an input voltage, which is generated internally from an externally applied supply voltage by a voltage generator circuit. The current generator circuit is connected to an output terminal via an interconnect. A first current flows on the interconnect in a test operating state of the integrated circuit. The current generator circuit generates a first partial current in a first test cycle of a test operating state and a second partial current in a subsequent second test cycle. The partial currents are each superposed on the first current on the interconnect. Consequently, three currents occur at the output terminal during the test operating state. The internally generated input voltage of the current generator circuit is determined from the three currents and the reference voltage.

    Abstract: An integrated dynamic memory includes memory cells which are combined to form individual independently addressable units, and a control circuit for controlling a refresh mode for the memory cells. The memory cells can have their memory cell content refreshed. The control circuit is designed such that one or more units of memory cells can be subject to a refresh mode in parallel in a refresh cycle. The control circuit sets a number of memory cell units, which are to be refreshed in parallel in a refresh cycle based on a temperature reference value. A maximum possible operating temperature for a memory chip can be increased without additional restrictions on memory access.
