1. A page buffer, comprising:
a first charge/discharge circuit coupled to a bit line and configured to
store first bit line forcing information, and
apply a first bit line forcing voltage to the bit line based on the first bit line forcing information; and
a second charge/discharge circuit coupled to the bit line and configured to
store a second bit line forcing information, and
apply a second bit line forcing voltage, different from the first bit line forcing voltage, to the bit line based on the second bit line forcing information;
wherein the first bit line forcing voltage and the second bit line forcing voltage are both higher than a programming bit line voltage and lower than a programming-inhabit bit line voltage.
