Abstract
A memory controller includes a health grade determining circuit to determine a health grade of a memory block based on a combination of an error detecting result of data read from at least one page of the block and block information related to a degree of degradation of the block, and an IO ratio setting circuit. The IO ratio setting circuit sets, according to the determined health grade, an IO ratio between a host IO operation and an internal IO operation. The host IO operation exchanges data with the memory device in response to a request from a host and the internal IO operation exchanges data with the memory device in relation to a background operation. The memory controller performs the host IO operation and the internal IO operation with the memory device according to the set IO ratio during a period in which the background operation is performed.
