Abstract
A memory system includes a first semiconductor memory device, a second semiconductor memory device, and a controller for controlling operations thereof. Each of the first and second semiconductor memory devices includes a normal area and a preliminary area. The controller is configured to determine a data migration operation on target data stored in the first semiconductor memory device and in response thereto control the first semiconductor memory device to read the target data, generate migration data including a plurality of group migration complete data indicating that the data migration operation has been partially completed based on the target data, and control the second semiconductor memory device to program the migration data in the preliminary area of the second semiconductor memory device.
