A storage device includes a journal buffer configured to store a plurality of pieces of journal data, the journal buffer including a plurality of bank pools and a journal data region, where each of the plurality of pieces of journal data includes a first data item corresponding to a bank address and a second data item corresponding to a row address and a memory controller configured to control the journal buffer to temporarily store first pieces of journal data from among the plurality of pieces of journal data of which the first data items are equal to each other in at least one of the plurality of bank pools and rearrange the first pieces of journal data based on results of a comparison between the second data items corresponding to the first pieces of journal data.

Memory controller for managing journal data, and operating method of the memory controller

An operating method of a memory controller that controls an operation of a memory device that includes a memory region and a repair memory region. The operating method may include receiving an address associated with the memory region that is included in a first read command and data read out from the memory region associated with the address, decoding the data using an error correction code and detecting an error included in the data, generating error type information indicating a type of an error included in the data, updating, based on the error type information, a count value associated with the address, the count value indicating a number of times that the type of error indicated by the error type information has occurred for the address, comparing the count value with a threshold value, and backing up the data that is stored in the memory region associated with the address to the repair memory region when the count value is equal to the threshold value.
