A page buffer includes a first register, a second register and a data I/O unit. The first register temporarily stores data to be programmed into cells included in a first memory cell block group, or reads and stores data of a corresponding memory cell. The second register temporarily stores data to be programmed into cells included in a second memory cell block group, or reads and stores data of a corresponding memory cell. The data I/O unit inputs specific data to the first register and the second register, or outputs data stored in the first register and the second register.
