    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.

    Abstract: An impedance calibration circuit includes a first variable impedance, a second variable impedance, a third variable impedance. The first variable impedance is connected to a ZQ terminal. A first control circuit performs a first impedance calibration on the first variable impedance based on an output signal from an output of a first comparator. A second control circuit performs a second impedance calibration on the third variable impedance based on an output signal from an output of a second comparator. A first switch connects an input of the first comparator to one of the ZQ terminal and the first node. A second switch connects the output of the first comparator to one of the first and second control circuits. A third switch connects an output of the first switch to one of first and second input terminals of the first comparator and connects the reference voltage to the other.

    Abstract: A memory device includes a memory cell array, a page buffer, a control logic circuit, a plurality of input/output pins, a data bus inversion (DBI) pin, and an interface circuit. The page buffer is connected to the memory cell array. The control logic circuit is configured to control an operation of the memory cell array. The plurality of input/output pins receive a plurality of data signals from the controller. The DBI pin receives a DBI signal from the controller. The interface circuit count a first number of bits having a logic value of 1 and a second number of bits having a logic value of 0 from the data signals and the DBI signal and provide the data signals to the page buffer or the control logic circuit based on the first number and the second number.
