Pre-charging two or more sets of nodes to set a differential output of a multi-input summation latch connected to the two or more sets of nodes in a pre-charged state, the two or more sets of nodes comprising a set of data signal nodes and a set of DFE correction nodes, in response to a sampling clock, generating a differential data voltage and an aggregate differential DFE correction signal, andgenerating a data decision by driving the differential output of the multi-input summation latch into one of two possible output states according to a summation of the differential data voltage signaland the aggregate differential DFE correction signal and subsequently holding the data decision by holding the differential output of the multi-input summation latch in a latched state for a durationdetermined by the sampling clock. 对两组或更多组节点进行预充电，以将与该两组或更多组节点连接的多输入求和锁存器的差分输出设置于预充电状态，所述两组或更多组节点包括一组数据信号节点和一组DFE校正节点；响应于采样时钟，生成差分数据电压以及总差分DFE校正信号；以及根据所述差分数据电压信号和总差分DFE校正信号的和将所述多输入求和锁存器的差分输出驱动至两种可能输出状态当中的一种来生成数据判定结果，以及随后通过将所述多输
