  • Patent number: 11830573
    Abstract: A memory device includes a first receive circuit to receive a control signal of a memory access request from a memory controller. A second receive circuit receives a timing signal from the memory controller. The memory device includes circuitry to transmit, during a calibration mode of operation, feedback to the memory controller along a data path, the feedback indicative of a phase relationship been the control signal and the timing signal.

  • Patent number: 11790962
    Abstract: A memory controller includes an interface to receive a data strobe signal and corresponding read data. The data strobe signal and the read data correspond to a read command issued by the memory controller, and the read data is received in accordance with the data strobe signal and an enable signal. A circuit in the memory controller is to dynamically adjust a timing offset between the enable signal and the data strobe signal, and control logic is to issue a supplemental read command in accordance with a determination that a time interval since a last read command issued by the memory controller exceeds a predetermined value.

  • Publication number: 20220343956
    Abstract: A memory controller having a time-staggered request signal output. A first timing signal is generated while a second timing signal is generated having a first phase difference relative to the first timing signal. An address value is transmitted in response to the first timing signal and a control value is transmitted in response to the second timing signal, the address value and control value constituting portions of a first memory access request.
