Abstract
A method is provided for controlling a write operation in a nonvolatile memory device to provide wear leveling, where the nonvolatile memory device includes multiple memory blocks. The method includes reading write indication information with respect to at least a selected memory block of the multiple memory blocks; determining whether a write order of data to be stored in the selected memory block is an ascending order or a descending order, based on the write indication information of the selected memory block; and generating addresses of memory regions in the selected memory block in an ascending order when the write order of the data is determined to be an ascending order, and generating addresses of the memory regions in the selected memory block in a descending order when the write order is determined to be a descending order.
