DATA DETECTION CIRCUIT AND DATA DETECTION METHOD

PROBLEM TO BE SOLVED: To provide a data detection circuit and a data detection method for quickly detecting in input N-bit binary data a first bit having firstly a first logical value and then a second bit having the first logical value. SOLUTION: This data detection method comprises a step for receiving the N-bit input data in response to the clock signal, detecting the first bit having firstly the first value in the received N-bit input data and outputting N-bit middle data generated by changing solely the bit value detected by the N-bit bit input data, and a step for receiving the N-bit middle data in response to the reversed clock signal, detecting the second bit having firstly the first value in the received N-bit middle data and outputting the result.
