Abstract
A memory controller and a method of operating the same may provide recovery from a Sudden Power-Off (SPO). The memory controller may control a memory device including a plurality of memory blocks, each memory block having a plurality of pages. The memory controller may include a dummy program controller configured to, after an SPO has occurred while a program operation was being performed on a page of the memory device, control a dummy program operation for recovering from the SPO; a parity data controller configured to control resetting and generation of parity data for chipkill decoding based on pages on which the dummy program operation is determined to be performed; and a valid data controller configured to control movement of valid data based on a number of pages on which the dummy program operation is to be performed.
