  • Patent number: 11996162
    Abstract: Systems and methods that may enable alignment of a receiver enable signal with one or more clocking signals. By aligning the receiver operations with the one or more clocking signals, a likelihood of a false or incorrect data capture may be reduced, which may improve operation of a memory system. Reducing a likelihood of incorrect data capture may increase an accuracy of a distortion correction operation of a decision feedback equalizer (DFE).

  • Patent number: 11855812
    Abstract: A keeper device is used in a hybrid loop unrolled DFE circuit to selectively output signals from equalizers corresponding to a specific possibility of the values of the previous bit (e.g., logical high or logical low) when DFE technique is not used. Those equalizers corresponding to possibilities other than the specific possibility of the values of the previous bit are disabled in the hybrid loop unrolled DFE circuit. As such, the hybrid loop unrolled DFE circuit saves power when the DFE technique is not used since only a portion of the total equalizers in the hybrid loop unrolled DFE circuit are powered.
