    摘要: A nonvolatile memory device performs interleaving of data to be stored in each wordline (memory page), or of data to be stored in multiple wordlines (memory pages). The NVM includes a memory cell array, a storage circuit of a de-interleaving circuit, and a read/write circuit. The storage circuit of the de-interleaving circuit is configured to store program data to be written interleaved into the memory cell array. The read/write circuit is configured to control the interleaved/deinterleaved data input/output between the memory cell array and the storage circuit. The write operation unit size may be the same or different from the read operation unit size. The storage circuit stores the program data of integer k times of a common divisor of a read operation unit size and a write operation unit size of the read/write circuit, wherein k may equal ‘m’ (the number of bits stored in each memory cell of the NVM).
