Storage device and an electronic system including the same

Abstract

A storage device and an electronic system including the same semiconductor device are provided. The storage device includes a non-volatile memory device configured to store data in a data area and metadata corresponding to the data in a spare area distinguished from the data area, and a memory controller configured to perform a translation operation of translating a logical address received from an outside to a physical group address, receive first and second metadata different from each other from the non-volatile memory based on the physical group address, and perform an index check operation of selecting a piece of metadata corresponding to the logical address from the first and second metadata.

Dependencies are inferred from the claim text.
