Abstract:
1. A method of copying a page in a memory device having a plurality of memory blocks and a plurality of sets of bit lines, each of the plurality of memory blocks including a plurality of pages, and each set of bit lines corresponding to a respective memory block, wherein first bit lines of a source memory block that includes a source page are respectively coupled to second bit lines of a target memory block that includes a target page, the method comprising: disconnecting the first bit lines of the source memory block from the second bit lines of the target memory block; transferring data stored in the source page to the first bit lines of the source memory block; transferring the data from the first bit lines of the source memory block to the second bit lines of the target memory block by connecting the first bit lines of the source memory block to the second bit lines of the target memory block; and writing the data transferred to the second bit lines of the target memory block into the target page, wherein, in a case that the target memory block is adjacent to the source memory block, transferring the data from the first bit lines of the source memory block to the second bit lines of the target memory block includes: disconnecting the second bit lines of the target memory block from bit lines of a memory block adjacent to the target memory block in an opposite direction of the source memory block; turning off an equalizer of the target memory block; and connecting the first bit lines of the source memory block to the second bit lines of the target memory block.
