Abstract: A method of controlling the operation of a memory controller includes, in a read operation of a non-volatile memory device, the memory controller counting a selected read count of a selected string in a selected memory block and/or counting a non-selected read count of a non-selected string in the selected memory block. The memory controller performs a reclaim operation of the selected memory block when the selected read count and/or the non-selected read count exceeds a read threshold. To move data of the selected memory block to another memory block by the reclaim operation, the memory controller may copy the data of the selected memory block to another block by using a changed page address.
