Abstract
The memory device is comprised of a plurality of memory arrays. Firstly, one of the memory arrays is selected for operation. When the selected one reaches an operational limit due to repetition of data rewriting which causes degradation of writing performance, another memory array is then selected for subsequent operation to thereby improve performance of the semiconductor nonvolatile memory device.
