Storage device with improved map update speed and operating method thereof

Provided herein may be a storage device and an operating method the storage device. The storage device includes a memory controller having a map manager and preload mapping information storage, and amemory device having logical-to-physical mapping information. The memory controller determines and obtains from the memory device, preloads mapping information, and then stores the preload mapping information in the preload mapping information storage, before a map update operation of the logical-to-physical mapping information is performed. The preload mapping information includes logical-to-physical mapping information to be updated. 本发明可提供一种存储装置以及操作该存储装置的方法。该存储装置包括：存储器控制器，具有映射管理器和预加载映射信息存储装置；以及存储器装置，具有逻辑到物理映射信息。存储器控制器确定预加载映射信息并且从存储器装置获得预加载映射信息，然后在执行逻辑到物理映射信息的映射更新操作之前，将预加载映射信息存储在预加载映射信息存储装置中。预加载映射信息包括待更新的逻辑到物理映射信息。
