    摘要: Systems and methods to set a voltage value associated with a memory controller coupled to a memory device are disclosed. A particular method includes comparing test data of a test path to functional data of a functional path. The functional data may be generated based on device data received at a memory controller from a memory device. The test data may be affected by a voltage value applied to a resistor arrangement in electronic communication with the test path. The voltage value may be applied to the resistor arrangement based on the comparison.

    摘要: Systems and methods to set a voltage value associated with a communication bus that includes memory controller coupled to a memory device are disclosed. A particular method may include performing a first calibration operation associated with first data written from a memory controller to a memory device. A second calibration operation may be associated with second data read at the memory controller from the memory device. The operating parameter may be set based on a result of at least one of the first and the second calibration operations at the memory device or the memory controller.

    摘要: A phase locked loop generates an output corresponding to a source synchronous input and an input link clock signal. A phase locking feedback system receives the input and an input link clock signal and detects phase deviations between the output and the input. The phase locking feedback system also adjusts an adjusted clock signal based on the phase deviations thereby causing the phase locking feedback system to generate the output so that the output has a steady phase relationship with the input. A first mechanism causes the phase locking feedback system not to track phase deviations between the output and the input upon occurrence of a first predefined event, thereby maintaining the adjusted clock signal at a current state.
