A storage device of the present disclosure includes a memory device configured to store a plurality of address maps indicating a mapping relationship between a logical address and a physical address, and a memory controller configured to, when the storage device is in a power on state from a power off state, determine a priority rank of each of the plurality of address maps based on file attribute information received from a host and sequentially load the plurality of address maps according to the priority rank.

Memory controller, storage device, and method of operating the same

The present technology provides a method of operating a host communicating with a memory system including a journal area and a data area. The method of operating the host includes determining to update old data stored in the memory system, transferring, to the memory system, a write command for writing journal data and meta journal data for updating the old data to the journal area, and transferring, to the memory system, a write command for writing new data corresponding to the journal data to the data area in response to a write completion of the meta journal data and the journal data received from the memory system. Each of the meta journal data and the journal data includes a descriptor identifier (ID) indicating the same write transaction.

Method of operating host and memory system connected thereto

A storage device may include: a memory device including a temperature sensor; and a memory controller for acquiring, from the memory device, temperature information sensed by the temperature sensor for a temperature management period, performing a performance limiting operation of limiting the performance of the memory device according to the temperature information, calculating the temperature management period by using the temperature information, and updating the temperature management period by using history information on a performance history of the performance limiting operation.
