  • Publication number: 20210265004
    Abstract: A memory device includes memory blocks, a read count storage, a cell counter, and a read reclaim processor. The read count storage stores read count information including read counts of the memory blocks. When a read count of a target block among the memory blocks exceeds at least one threshold count, the cell counter performs a read operation on at least one page among pages included in the target block by using a first read voltage, and calculates a first memory cell count as a number of memory cells read as first memory cells among memory cells included in the at least one page, based on a current sensed from the at least one page in the read operation. The read reclaim processor provides a memory controller with a status code based on the first memory cell count and a number of correctable error bits.
