Abstract: A comparator unit is used to compare an actual transmission time signal with a nominal transmission time signal and to produce a difference signal from the discrepancy, from which difference signal a correction signal is produced in a control unit. This correction signal is used to control a correction unit, which compresses or extends an applied input data signal, thus changing the phase angle of the output data signal so as to minimize the discrepancy between the transmission times. The discrepancy is corrected independently of the system clock, and the correction speed is set variably.

Abstract: A method for selective masking is described. In this case, a filling material is applied to a structure which, as a function of the aspect ratio of the structure, forms cavities when the aspect ratio is high. The filling layer is then removed as far as the cavities and, using an etching process, filling material is removed completely from the recesses in which the cavities are formed. In this way, areas are exposed selectively.
Abstract: A compensation circuit for a digital/analogue converter, which is clocked by a clock signal comprising a jitter and converts a digital input data signal into an analogue output data signal comprising a jitter error due to said jitter, comprises a measurement circuit for measuring the jitter and a modelling circuit for generating a digital modelled jitter error signal which simulates the jitter error dependent on the measured jitter and the digital input data signal, wherein the digital modelled jitter error signal is subtracted from the digital input data signal.

Abstract: An integrated circuit, in particular, an integrated memory, contains a control circuit for ascertaining an operating state of the circuit. A self-repair circuit, which is connected to the control circuit, is used to implement self-test and self-repair operation for checking the functioning of, and repairing, defective circuit sections of the integrated circuit. After a supply voltage has been applied to the integrated circuit, the control circuit ascertains an operating state of the integrated circuit and, in a manner dependent thereon, the self-repair circuit is activated by the control circuit in a self-controlling manner in order to put the integrated circuit into a self-repair mode for implementing self-test and self-repair operation. The integrated circuit can be tested for its functionality and repaired even after being soldered onto a module substrate.

Abstract: The inventive memory circuit comprises a main memory block and a substitution memory block for substitution of defect memory cells, with the substitution memory block being external to the main memory block. The substitution memory block is arranged to substitute at least one bitline-related or wordline-related set of memory cells being connected to the same bitline or wordline, respectively. Furthermore, the inventive memory circuit comprises redirection means for redirecting the access to a memory cell of the at least one respective substituted set of memory cells to the substitution memory block.
Abstract: The invention relates to a method for generating very short gate structures. In a method for generating a structure on a substrate in accordance with one embodiment of the invention, first of all a layer sequence of a first oxide layer, a first nitride layer and a second oxide layer is disposed onto the substrate. Subsequently, a portion of the second oxide layer and a portion of the first nitride layer is removed in order to expose a portion of the first oxide layer. Then, a part of the first nitride layer above the first oxide layer and below the second oxide layer is removed in order to expose the area of the structure.

Abstract: A memory circuit comprises a memory and a first test circuit coupled to the memory. The first test circuit is configured to compare data read from memory cells with expected data for the memory cells to provide a first set of pass/fail signals for the memory cells, compress the first set of pass/fail signals for the memory cells into a second pass/fail signal, latch the second pass/fail signal in response to a data valid signal, maintain the latch of the second pass/fail signal if the second pass/fail signal indicates a failed test, combine the second pass/fail signal and a third pass/fail signal of a second test circuit to provide a fourth pass/fail signal, and pass the fourth pass/fail signal to a third test circuit.

Abstract: A multithreaded processor includes a thread ID for each set of fetched bits in an instruction fetch and issue unit. The thread ID attaches to the instructions and operands of the set of fetched bits. Pipeline stages in the multithreaded processor stores the thread ID associated with each operand or instruction in the pipeline stage. The thread ID are used to maintain data coherency and to generate program traces that include thread information for the instructions executed by the multithreaded processor.
