  • Publication number: 20200194042
    Abstract: A system has a plurality of memory devices arranged in a fly-by topology, each having on-die termination (ODT) circuitry for connecting to an address and control (RQ) bus. The ODT circuitry of each memory device includes a set of one or more control registers for controlling on-die termination of one or more signal lines of the RQ bus. A first memory device includes a first set of one or more control registers storing a first ODT value, for controlling termination of one or more signal lines of the RQ bus by the ODT circuitry of the first memory device, and a second memory device includes a second set of one or more control registers storing a second ODT value different from the first ODT value, for controlling termination of one or more signal lines of the RQ bus by the ODT circuitry of the second memory device.

  • Publication number: 20200195475
    Abstract: A receiver is equipped with an adaptive phase-offset controller and associated timing-calibration circuitry that together shift the timing for a data sampler and a digital equalizer. The sample and equalizer timing is shifted to a position with less residual inter-symbol interference (ISI) energy relative to the current symbol. The shifted position may be calculated using a measure of signal quality, such as a receiver bit-error rate or a comparison of filter-tap values, to optimize the timing of data recovery.

  • Patent number: 10651849
    Abstract: A memory control component outputs a memory write command to a memory IC and also outputs write data to be received via data inputs of the memory IC. Prior to reception of the write data within the memory IC, the memory control component asserts a termination control signal that causes the memory IC to apply to the data inputs a first on-die termination impedance during reception of the write data followed by a second on-die termination impedance after the write data has been received. The memory control component deasserts the termination control signal to cause the memory IC to apply no termination impedance to the data inputs.
