    摘要: According to example embodiments, a control method of a nonvolatile memory device, which includes a plurality of memory blocks on a substrate, each memory block including a plurality of sub blocks stacked in a direction perpendicular to the substrate and being configured to be erased independently and each sub block including a plurality of memory cells stacked in the direction perpendicular to the substrate. The control method includes comparing a count value of a first memory block with a reference value, the count value determined according to the number of program, read, or erase operations executed at the first memory block after data is programmed in the first memory block; and if the count value is greater than or equal to the reference value, performing a reprogram operation in which data programmed in first the memory block is read and the read data is programmed in a second memory block.

    摘要: An operating method of a nonvolatile memory device is provided which sequentially performs a plurality of erase loops to erase at least one of a plurality of memory blocks. The operating method comprises performing at least one of the plurality of erase loops; performing a post-program operation on the at least one memory block after the at least one erase loop is executed; and performing remaining erase loops of the plurality of erase loops. The post-program operation is not performed when each of the remaining erase loops is executed.
