Abstract: Disclosed is a method for operating a memory controller. The method for operating the memory controller includes the steps of: determining the number of free blocks to be generated for idle time by using a block consumption history; and controlling a nonvolatile memory device to perform a garbage collection operation for the idle time for generating the free blocks corresponding to the determined number of the free blocks. [Reference numerals] (S10) Determining the number of free blocks; (S100) Determining the number of effective pages to be copy-back; (S110) Performing a garbage collection operation; (S120) Performing a write operation corresponding to a third write request; (S20) Performing the garbage collection operation for idle time; (S30) Receiving a first write request and a second write request; (S40) Performing the write operation by responding to the first write request; (S50) Remaining number of free blocks> Number of threshold free blocks?; (S60) Generating one new free block; (S70) Performing the write operation corresponding to the second write request; (S80) Receiving the third write request; (S90) Garbage collection operation is completed for the idle time?

Abstract: PURPOSE: A nonvolatile memory device with improved durability and an operating method thereof are provided to improve update durability by performing a wear leveling based on the format conversion of meta data. CONSTITUTION: A memory unit(3200) stores user data and meta data. A memory controller(3100) accesses the memory unit in response to a request from an external host, generates meta data to be written in the memory unit, and converts the format of the meta data based on the access counting result of the memory unit. A meta data providing unit(3120) includes a meta data generating unit(3121), a signature generating unit, and a format converting unit.

CONSTITUTION: The recording number of units included in Blocks of a base area is counted. A unit which the recording number is more than a reference value is selected(S330). The unit of the selected base area is mapped on the unit included in a log area(S340). A recording request for the unit of the mapped base area is received. A recording process is executed in the unit of the mapped log area(S350). The recording number for the unit of the mapped log area is counted.
