    Abstract: A memory device correcting a data strobe signal when performing a write operation includes a correction circuit configured to receive the data strobe signal and to generate a reference delay for the received data strobe signal, and a main circuit configured to correct the data strobe signal based on the reference delay generated by the correction circuit. The correction circuit includes a delay cell configured to generate a reference delay for the data strobe signal received by the main circuit and to store the generated reference delay, when a data signal is input to the main circuit, a first counter configured to adjust the reference delay, and a second counter configured to determine a delay of the data strobe signal received by the main circuit, when a write operation is performed.

    Abstract: A memory package includes a plurality of memory chips, and an interface chip relaying communications between a controller and the plurality of memory chips and receiving a plurality of signals from the plurality of memory chips. The interface chip includes receivers outputting a data signal and a raw clock signal based on the plurality of signals, a delay circuit outputting a delay clock signal by applying an offset delay corresponding to ½ of one unit interval of the data signal and an additional delay to the raw clock signal, and a sampler sampling the data signal in synchronization with a clock signal. The delay circuit outputs the clock signal generated by removing the offset delay from the delay clock signal when the delay clock signal and the data signal have a phase difference corresponding to one unit interval of the data signal.
