Abstract
A memory device includes a clock receiving block, a data transceiver block, a phase detection block, and a phase information transmitter. The clock receiving block is configured to receive a clock signal from a memory controller through a clock signal line and generate a data sampling clock signal and an edge sampling clock signal. The data transceiver block is configured to receive a data signal from the memory controller through a data signal line. The phase detection block is configured to generate phase information in response to the data sampling clock signal, the edge sampling clock signal and the data signal. The phase information transmitter is configured to transmit the phase information to the memory controller through a phase information signal line that is separate from the data signal line.
