Abstract: A memory controller controlling a nonvolatile memory device having a plurality of memory blocks as a data storage space includes an error detection and correction circuit and a reclaim control unit. The error detection and correction circuit receives data from a memory block and calculates a comparison result by comparing a bit error rate of the received data and a predetermined value. The reclaim control unit determines whether or not to perform a read reclaim operation depending on the comparison result and a read voltage used to read the data. The read reclaim operation copies the data to a memory block different from a memory block having stored the data.

Abstract: A memory system comprises a nonvolatile memory comprising a memory block having multiple pages, and a controller configured to control the nonvolatile memory to store data in the memory block according to a command and logical address received from an external source. The controller is configured to determine whether the logical address is currently mapped to a bad page of the memory block by referring to a bad page map, and as a consequence of determining that the logical address corresponds to the bad page, remaps the logical address to a different page and stores dummy data in the bad page.
