Memory controller and method of ordering sequential data and random data
Abstract:
A memory controller includes a meta data memory configured to store mapping information of data stored in a plurality of memory blocks included in a memory device and valid data information indicating whether the data stored in the plurality of memory blocks is valid data, and a migration controller configured to control the memory device to perform a migration operation of moving a plurality of valid data stored in a source memory block among the plurality of memory blocks from the source memory block to a target memory block based on the mapping information and the valid data information.
