    • Provided is an integrating receiver having an adaptive decision feedback equalizer function and a system having the same. The integrating receiver can simultaneously remove an inter-symbol interference (ISI) and high frequency noises in a high speed DRAM data transmission system. The integrating receiver reduces a probability of wrong decision of data in a state in which the ISI that exists in a channel is removed so as to increase a signal-to-noise ratio (SNR) of a receiver, so that a maximum operation speed increases even in an environment with heavy noises. There is also provided a method of obtaining an equalizer coefficient suitable for the integrating receiver and a method of obtaining a reference voltage by using an integrator in a single ended transmission method. In addition, in order to increase a decision feedback equalizer speed, a look-ahead method is used. In this method, flip flops with a high speed including multiplexers are used. Accordingly, the present invention can be applied to not only a DRAM interface system but also a serial communication between chips.
