    摘要: A method of controlling an analog signal in an integrated circuit includes generating a first control signal having a first predetermined duration within the integrated circuit. The first control signal is configured to cause the analog signal to have a first signal level. The first signal level is compared to a level of a target signal. A second control signal is generated within the integrated circuit based on a result of the comparison. The second control signal is configured to cause the analog signal to have a second signal level. The second control signal has a second predetermined duration that is different than the first predetermined duration.

    摘要: A calibration apparatus is provided for adjusting the relative phase between two signals received at a memory chip, the two signals being generated such that they are synchronized with one another in a controller and are transmitted to the memory chip via separate lines. The calibration apparatus comprises a measuring device, which is arranged in the memory chip and is designed for measuring the relative phase between the two received signals, and a feedback loop containing a phase-controlling correction device. The measuring device is designed for generating an item of control information indicating the deviation of the measured relative phase from a defined tolerance range. The correction device responds to the control information to compensate for the deviation. The correction device is arranged in the controller and is designed for influencing the relative phase between the two signals to be transmitted to the memory chip. The feedback loop contains a signal connection leading from the memory chip to the controller.

    摘要: A Phase shifter for generating a phase-shifted, in particular phase-delayed, output signal from an input signal is disclosed. In one embodiment, the phase shifter includes a first delay line and at least one further delay line with respectively cascaded delay elements that form a U-shaped signal path along which at least one delay element is adapted to be controlled to be optionally opening or closing. A phase discriminator located at the input side of which a clock signal and a signal from one of the delay lines can be applied, and the output side of which is connected with a respective control input of the delay elements. The clock signal can also be applied to the first delay line, so that a feedback loop is formed by the phase discriminator and at least one of the delay lines. The input signal can be applied to the delay line whose signal output is not connected with the phase discriminator, and the output signal can be output therefrom.

    摘要: The invention relates to a semiconductor memory module having a plurality of memory chips arranged next to one another in a row. The memory module has a module-internal clock, command/address and data bus which transfers clock signal, command and address signals and also data signals from a memory controller device to the memory chips and data signals from the memory chips to the memory controller device. The memory module has respective clock, command/address and data signal lines. The clock signal lines comprise two differential clock signal lines which, at their end opposite to the memory controller device are either open or connected to one another by a short-circuiting bridge. The memory chips, during a write operation, synchronize the write data with the clock signal running from the memory controller device to the end of the clock signal line and, during a read operation, output the read data synchronously with the clock signal reflected from the open or short-circuited end of the clock signal lines.
