Abstract
Some embodiments include an apparatus including a first node to receive an input data signal including a first edge, and a second edge occurring after the first edge; a second node to receive a strobe signal including an edge; a first circuit to generate a modified strobe signal based on the strobe signal, the modified strobe signal including an edge occurring after the edge of the strobe signal; a second circuit to generate a modified data signal based on the input data signal, the modified data signal including an edge occurring after the second edge of the input data signal; and a third circuit to respond to the modified strobe signal and generate an output data signal based on the modified data signal.
