CONTROLLER FOR A MEMORY, A STORAGE SYSTEM INCLUDING THE SAME, AND A METHOD FOR MEASURING A LIFETIME OF THE MEMORY BY COMPARING INITIAL OPERATION TIME WITH THE PERIODICALLY MEASURED OPERATION TIME OF THE MEMORY

摘要

PURPOSE: A controller for a memory, a storage system including the same, and a method for measuring a lifetime of the memory are provided to accurately measure a lifetime of a nonvolatile memory based on the program time or erase time of the nonvolatile memory.;CONSTITUTION: The initial operation time of a memory is measured(S410). The initial operation time is stored(S420). The operation time of the memory is measured(S430). Lifetime information is generated by comparing the measured operation time with the initial operation time(S440).;COPYRIGHT KIPO 2012
