Abstract: A memory device includes a multiphase clock generator which generates a plurality of divided clock signals, a first error correction block which receives a first divided clock signal among the plurality of divided clock signals, a first data multiplexer which transmits first least significant bit data corresponding to the first divided clock signal, a second error correction block which receives the first divided clock signal, and a second data multiplexer which transmits first most significant bit data corresponding to the first divided clock signal. The first error correction block receives the first least significant bit data and corrects a toggle timing of the first least significant bit data. The second error correction block receives the first most significant bit data and corrects a toggle time of the first most significant bit data.
