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.
