    摘要: A method and system for generating a reference voltage for memory device signal receivers operates in either a calibration mode or a normal operating mode. In the calibration mode, the magnitude of the reference voltage is incrementally varied, and a digital signal pattern is coupled to the receiver at each reference voltage. An output of the receiver is analyzed to determine if the receiver can accurately pass the signal pattern at each reference voltage level. A range of reference voltages that allow the receiver to accurately pass the signal pattern is recorded, and a final reference voltage is calculated at the approximate midpoint of the range. This final reference voltage is applied to the receiver during normal operation.

    摘要: The present invention includes phase shifters, interrogators, methods of shifting a phase angle of a signal, and methods of operating an interrogator. One aspect of the present invention provides a phase shifter including a first power divider configured to receive a signal and provide plural quadrature components of the signal; plural mixers coupled with the first power divider and configured to scale the quadrature components using a phase shift angle; and a second power divider coupled with the mixers and configured to combine the scaled quadrature components to shift the phase angle of the input signal by the phase shift angle.

    摘要: A memory module is coupled to a number of controllers. The memory module is configured to configure each of a number of data input/output ports thereof as at least one of an input and an output in response to a first command from a particular controller of the controllers. The memory module is configured to partition itself into memory partitions in response to a second command from the particular controller so that each memory partition corresponds to a respective one of the controllers. Each of a number of data input/output ports of the controllers is configurable as at least one of an input and an output to correspond to a respective one of the input/output ports of the memory module. The first and second commands may originate from the particular controller, or the controllers may be coupled in parallel to the memory module.
