  • Patent number: 8296540
    Abstract: A method and apparatus for adjusting the performance of a memory system is provided. A memory system comprises a master device and a slave device. A memory channel couples the master device to the slave device such that the slave device receives the system operating information from the master device via the memory channel. The slave device further includes tuning circuitry within the slave device such that the performance of the memory system is improved.

  • Patent number: 7308044
    Abstract: A technique for receiving differential multi-PAM signals is disclosed. In one particular exemplary embodiment, the technique may be realized as a differential multi-PAM extractor circuit. In this particular exemplary embodiment, the differential multi-PAM extractor circuit comprises an upper LSB sampler circuit configured to receive a differential multi-PAM input signal and a first differential reference signal, and to generate a first differential sampled output signal. The differential multi-PAM extractor circuit also comprises a lower LSB sampler circuit configured to receive the differential multi-PAM input signal and a second differential reference signal, and to generate a second differential sampled output signal.

  • Patent number: 6448813
    Abstract: An output driver circuit for driving a signal onto a signal line. The output driver circuit comprises at least one driver circuit and a passive network. The passive network is configured to limit the variation in the output impedance of the output driver circuit. The output driver circuit thus provides an output impedance that closely matches the loaded impedance of the signal line at all times so as to minimize secondary reflections on the signal line.
