Abstract
A page buffer includes a pre-charge unit for pre-charging a bit line of a selected memory cell of a memory cell array via a first pre-charge line and pre-charging a sensing node via a second pre-charge line, during a pre-charge time, a bit line connection unit connected between the bit line and the sensing node and including a connecting node connected to the first pre-charge line, the bit line connection unit controlling a voltage of the sensing node, during a develop time, based on a bit line connection control signal and a sensing node voltage control signal, and a data input and output unit for generating sensing data by sensing a level of the voltage of the sensing node, during a sensing time.
