Abstract
A storage system includes a non-volatile memory (NVM) device, having a memory cell array, and a storage controller. The storage controller receives a write command and data from a host and controls the NVM device to write the data in the memory cell array. Additionally, the storage controller determines a memory region of the memory cell array in which the data will be written, clusters a plurality of word lines into a plurality of groups on the basis of feature information of the plurality of word lines, rearranges an access order in units of groups according to the feature information, and accesses the word lines in the rearranged order to write the data in the memory region.
