ABSTRACT:
A method for operating a page buffer of a nonvolatile memory device reduces errors while transferring data between latches and shortens a copy-back programming time. The copy-back program is carried out using one among several latch circuits included in the page buffer. The method activates a first latch circuit while inactivates a second latch circuit, in a copy-back programming operation, and activates the first and second latch circuits in programming, reading, and verifying operations.
