  • Patent number: 7466761
    Abstract: A configuration for the transmission of signals includes a data processing device and a functional unit, which are connected to a first and second bus system, respectively, for the respective transmission of signals with different frequencies. A transmission unit is connected to the data processing device through the first bus system and to the functional unit through the second bus system, for the transmission and conversion of signals between the data processing device and the functional unit. It additionally serves for the electrical decoupling of the first bus system and the second bus system. As a result, independently of the electrical properties of the functional unit, a high data throughput is made possible in conjunction with still good detectability of the signals to be transmitted.

  • Patent number: 7372749
    Abstract: In a method for repairing a memory component, data retention times of regular memory cells are determined. Weak regular memory cells having a data retention time that is shorter than a predetermined limit value are determined. A device is programmed in such a manner that a write or read access to the weak regular memory cell is simultaneously also effected for a redundant memory cell in order to jointly read from, or write to, the weak regular memory cell and the redundant memory cell.

  • Patent number: 7359259
    Abstract: Apparatuses and methods for transmitting and receiving a data signal on a line pair having a first transmission line and a second transmission line are provided. In one embodiment, a data signal which represents the data to be transmitted by means of a sequence of first and second signal levels is applied to the first transmission line, and a reference signal which changes between a first and a second reference level only when a level change between the first and the second signal level is suppressed between two successive signal levels of the data signal on the first transmission line is applied to the second transmission line.

  • Patent number: 7349286
    Abstract: A memory component comprises a plurality of memory cells that are each assigned an address, and an address memory for storing numerical values which are uniquely related to addresses of defective memory cells. An address converter having an input for receiving a first address and an output for outputting a second address is designed in such a way that the second address output at its output is dependent on the first address received at its input and on the numerical values stored in the address memory, each first address being uniquely assigned a second address. An address bus, which is connected to the output of the address converter, transfers the second address to an input of an address decoder, which is designed for selecting a memory cell to which the second address is assigned.

  • Patent number: 7325182
    Abstract: The invention relates to a method for testing electrical modules. A test pattern of input signals is applied to each module to be tested as test specimen, and the actual responses of the test specimen to the test pattern is compared with the desired responses. The comparison result is evaluated for the purpose of displaying test assessments. According to one embodiment of the invention, to supply the desired responses, a reference module produced with the same design and technology as the test specimen and tested as entirely satisfactory is utilized. The same test pattern as for the test specimen is applied to the reference module. The invention furthermore relates to circuit arrangements for carrying out this method, in particular for testing data memories.

  • Patent number: 7231488
    Abstract: A system and method are provided for reducing a rate for refreshing a portion of a dynamic random access memory (DRAM). The method includes storing a information for distinguishing between a first portion of a DRAM requiring refresh at a first rate and a second portion of said DRAM permitting refresh at a second rate lower than the first rate. The stored information is then accessed to refresh the first portion of the DRAM at the first rate and to refresh the second portion at the second rate. The information can be generated from post-fabrication stress testing such that most of the DRAM can be refreshed at the lower rate and only the portion requiring more frequent refresh is refreshed at the higher rate.

  • Patent number: 7170798
    Abstract: Active control of body contacts in memory devices can provide variable substrate voltages during device operation. The body contacts can be used to adjust the body bias of switches in activated memory cells, while maintaining the body bias of switches in inactive memory cells. This can reduce the body effect (i.e., variation of the threshold voltage due to a variation of the substrate or bulk voltage) and can therefore provide improved array device performance (e.g., reduced data corruption) while the word line (“WL”) is activated.
