Disclosed is a caller ID mobile terminal which allows a user to exactly identify a caller. The user can exactly recognize the caller as voices directly recorded and stored by the user by individual or voices reading nicknames entered in text ring as bell tones, and further the user can be amused by using various versions of voices as bell tones through emoticons or the like.

A pulse-based flip-flop that latches a data input signal to convert the data input signal into a data output signal in response to a clock signal. The pulse-based flip-flop comprises a latch that latches the data input signal in response to a first clock pulse signal and a second clock pulse signal and a pulse generator including a NAND gate, a variable delay, and a first inverter, the pulse generator receives the clock signal to generate the first clock pulse signal and the second clock pulse signal. The NAND gate receives the clock signal and an output signal of the variable delay and outputs the second clock pulse signal. The first inverter receives the first clock pulse signal and outputs the second clock pulse signal. The variable delay receives the clock signal and the second clock pulse, and an output signal of the variable delay feeds back to the NAND gate.

A scan flip-flop circuit includes a pulse generator, a dynamic input unit and a latch output unit. The pulse generator generates a pulse signal which is enabled in synchronization with a rising edge of a clock signal in a normal mode, and is selectively enabled in synchronization with the rising edge of the clock signal in response to a logic level of a scan input signal in a scan mode. The dynamic input unit precharges a first node to a power supply voltage in a first phase of the clock signal, selectively discharges the first node in the normal mode, and discharges the first node in the scan mode. The latch output unit latches an internal signal provided from the first node to provide an output data, and determines whether the output data is toggled based on the clock signal and a previous state of the output data.
