Abstract
A memory controller, for controlling a memory device including a plurality of memory blocks, includes a garbage collection controller configured to determine candidate blocks in which valid data is equal to or less than a predetermined ratio among the plurality of memory blocks, and configured to determine at least two or more memory blocks as victim blocks among the candidate blocks based on information on blocks that may be simultaneously erased among the plurality of memory blocks. The memory controller also includes an operation controller configured to control the memory device to copy valid data stored in the victim blocks to a different memory block.
