Object storage system managing error-correction-code-related data in key-value mapping information

An object storage system comprising:

• a plurality of memory devices configured to store data that corresponds to a value;
• and
• a memory controller configured to,
• manage key-value mapping information that identifies a correspondence relationship between the value, a first key and a parity,
• receive a key from a host,
• determine that the received key corresponds to the first key,
• based on the determination, read, from the plurality of memory devices, the data that corresponds to the value that is identified by the key-value mapping information as having the correspondence relationship with the first key, and
• output the value to the host based on the read data,
• wherein the memory controller is further configured to detect an error of the read data based on the parity that is identified by the key-value mapping information as having the correspondence relationship with the value and the first key.

A memory system comprising:

• one or more memory devices;
• and
• a memory controller configured to,
• generate a table that,
• includes a first key identifying value data,
• includes a storage address of the value data within the one or more memory devices,
• includes parity data for performing error detection for the value data, and
• maps the first key to the storage address and the parity data, receive a key from a host, and
• when the received key corresponds to the first key,
• read the value data from the one or more memory devices using the storage address,
• perform the error detection on the read value data using the parity data, and
• output the read value data to the host.
