An electronic device is provided. The electronic device includes a processor, a volatile memory, and a storage. The processor is configured to, in response to a request for data included in a file, identify information of the file and a type of the request, configure a flag for the request if the file is determined to correspond to at least one in a list of a designated information table, identify, based on the flag, mapping information of a specific region, which includes a logical address of the data, in mapping information for mapping of logical addresses and physical addresses for the non-volatile memory of the storage, acquire, in response to the mapping information of the specific region existing in the volatile memory, a physical address of the non-volatile memory mapped to the logical address of the data, and transmit the request, including the acquired physical address of the non-volatile memory, to the storage.

Electronic device including storage and method of processing data request using mapping information stored in non-volatile memory loaded into volatile memory

The various embodiments disclose an electronic device including: a storage including a non-volatile memory having a buffer space and a storage space, a storage device controller, and a storage interface, and a processor. According to various embodiments, the processor may be configured to perform control to determine whether the storage supports a high speed data storage mode using a buffer space of a non-volatile memory of the storage, activate a function of writing data buffered in the buffer space of the non-volatile memory into a storage space of the non-volatile memory based on the storage interface operating in a first state based on the storage supporting the high speed data storage mode, and transition the storage interface of the storage to the first state based on no request to the storage being generated during a predetermined time period based on the storage interface operating in a second state.

Electronic device and method of utilizing storage space thereof

An electronic device may include a processor, a first volatile memory, and a storage including a nonvolatile memory and a second volatile memory. The processor may be configured to: identify information of a specific file and a kind of a request for data included in the specific file in response to a creation of the request for the data, set a flag in the request based on the identified information of the specific file, identify whether mapping information of a specific region including a logical address of the data among mapping information in which logical addresses and physical addresses for the nonvolatile memory are mapped onto each other is stored in the first volatile memory, determine whether to manage the mapping information of the specific region using the first volatile memory, and determine whether to update the mapping information of the specific region in the first volatile memory.
