    Abstract: A memory device including an interface to receive one or more clock signals and one or more data signal a dual-sensing stage dual-tail latch arranged at the interface. The dual-sensing stage dual-tail latch includes a sensing stage to sense a differential voltage between a first signal and a second signal and to provide a first differential voltage output and a second differential voltage output to a first node and a second node, respectively. The dual-sensing stage dual-tail latch includes a complimentary sensing stage arranged in parallel with the sensing stage and to sense the differential voltage between the first signal and the second signal, where a first complimentary differential output voltage and a second complimentary differential output of the complimentary sensing stage are coupled to the first node and the second node. The dual-sensing stage dual-tail latch includes a latch stage to receive the outputs from the first node and the second node.

    Abstract: A device including an equalizer that includes a first input configured to receive an input signal, a second input configured to receive a reference signal, and a third input configured to receive an adjustment signal. The equalizer also includes a first output configured to transmit a corrected signal, wherein the corrected signal is generated based on data outputs controlled via the input signal, the reference signal, and a clock signal, wherein the data outputs are modified based on the first adjustment signal, wherein corrected signal offsets inter-symbol interference on the input signal based on a data bit received at the first input prior to reception of the input signal.
