Patent number: 7024578Abstract: A memory apparatus includes a memory module array having several memory modules. Each memory module has a synchronization connection for receiving a synchronization signal for synchronizing the memory module relative to the other memory modules in the memory module array. This enables combining data bursts read from the memory modules into a data stream.Type: GrantFiled: November 22, 2002Date of Patent: April 4, 2006Assignee: Infineon Technologies AGInventor: Wolfgang Nikutta

Patent number: 6937953Abstract: A circuit configuration has a calibration circuit, which is connected to terminals for two digital signals and has outputs for two digital output signals which are each derived from one of the digital signals. The calibration circuit effects temporal control of a switching edge of one of the output signals using a control value. A comparison circuit generates a comparison signal which indicates that one of the output signals has a switching edge first relative to the other output signal. The calibration circuit has a control input, through which the control value, which is stored in a storage circuit, can be set using the state of the comparison signal of the comparison circuit. The circuit configuration makes it possible to compensate undesirable propagation time differences between the digital signals.Type: GrantFiled: April 4, 2001Date of Patent: August 30, 2005Assignee: Infineon Technologies AGInventor: Wolfgang Nikutta

Patent number: 6639846Abstract: A method and a circuit configuration for a dynamic semiconductor memory are described in which, in order to reduce the parasitic coupling effects between two adjacent bit lines, in particular between a read line and a reference line, the adjacent line is put at a predetermined potential during the read operation. As a result, the read signal, which is very small in the worst-case scenario, is not adversely influenced by the coupling capacitance, since the inactive adjacent line acts as capacitive shielding. Advantageously, the read signals of the various active bit lines cannot mutually influence one another. A further refinement of the invention provides for the potential to be kept at the magnitude of the precharge state.Type: GrantFiled: April 2, 2002Date of Patent: October 28, 2003Assignee: Infineon Technologies AGInventor: Wolfgang Nikutta

Patent number: 6256243Abstract: A monolithically integrated test circuit for testing a digital semiconductor circuit configuration that is formed on the same semiconductor chip and has a large number of elements to be tested. The test circuit has a test data pattern register for temporary storage of a test data pattern, a read and write circuit for writing and reading the data in the test data pattern register to and from the elements to be tested, and a comparison circuit. The comparison circuit tests for any difference between the data written to and read from the elements to be tested. The test circuit has a pattern variation circuit, which can be activated by an activation signal and varies the test data pattern from the test data pattern register before writing into the elements to be tested.Type: GrantFiled: August 17, 2000Date of Patent: July 3, 2001Assignee: Infineon Technologies AGInventors: Dominique Savignac, Wolfgang Nikutta, Michael Kund, Jan Ten Bröke

Patent number: 6107815Abstract: An apparatus for function testing of electronic circuits includes a tester array having a terminal. A test circuit has at least two resistor elements, a common circuit node connected to the resistor elements for connection to the terminal of the tester array, and terminals of the resistor elements each being remote from the circuit node for connection to a respective output of an electronic circuit to be tested. A testing method for function testing of electronic circuits with such an apparatus includes placing the electronic circuit into a state in which signals are present at an output of the electronic circuit to be tested. The electronic circuit is function tested with respect to a resultant signal being established at the common circuit node.Type: GrantFiled: February 23, 1996Date of Patent: August 22, 2000Assignee: Infineon Technologies AGInventors: Wolfgang Nikutta, Hartmut Schmokel, Gunther Kuchinke, Thomas von der Ropp, Rudolph Walter

Patent number: 5821804Abstract: An integrated semiconductor circuit includes a semiconductor substrate. A number of first potential buses carry a first supply potential of the semiconductor circuit during operation. A number of second potential buses carry a second supply potential of the semiconductor circuit during operation. A number of circuit portions formed on the substrate are each connected between one of the first and one of the second potential buses for being supplied with electrical voltage.
