ABSTRACT:
A page buffer of a non-volatile memory device and a method for programming and reading the same is provided. The page buffer includes a first latch unit and one or more second latch units for storing data, transfer units connected between the first latch unit and the second latch units for transferring the data stored in the first latch unit to the second latch units, a path select unit that that senses data from bit lines and stores the sensed data in the first latch unit, and, in a program operation, transfers the data from the first and second latch units to the bit lines, a sensing unit for allowing the path select unit to sense data or the data received from the bit lines to be stored in the first latch unit, and a data I/O unit.
