Abstract
An electronic device, and more particularly, a page buffer is provided. The page buffer includes a sensing node configured to sense a potential of a bit line coupled to a memory cell, a precharging circuit coupled to the sensing node and configured to precharge a potential of the sensing node to a first voltage during an evaluation operation on the memory cell, a discharging circuit coupled to the sensing node and configured to discharge the potential of the sensing node from the first voltage to a second voltage, and a latch circuit coupled to the discharging circuit and configured to store therein data sensed from the memory cell based on a result of comparing the potential of the sensing node with a reference voltage after the potential of the sensing node is discharged to the second voltage and a predetermined period elapses.
