METHOD OF COPY-BACK OPERATION FOR NON-VOLATILE MEMORY DEVICE

摘要

PURPOSE: A method of copy-back operation for a non-volatile memory device is provided to reduce a copy-back operation time by continuously performing a copy-back reading operation and a copy-back programming operation. CONSTITUTION: A source page address and a target page address are stored in a register. Input data is stored in the first latch of a page buffer(222). The data of the source page in the memory cell block is read out and is stored in the second latch of the page buffer. The input data stored in the first latch is transmitted to a second latch and is stored as a copy-back data. The copy-back data is transmitted to the target page of a memory cell block and is programmed.
