A method of operating a storage device which includes a non-volatile memory including a normal unit configured to store normal data and a swap unit configured to store swap data and a controller configured to control the non-volatile memory is provided. The method includes receiving the swap data and a unit selection signal for selecting the swap unit from a host; and processing the swap data according to a data processing policy of the swap unit and writing the processed swap data to the swap unit. The data processing policy of the swap unit may be different from a data processing policy of the normal unit.

Utilizing different data storage policies in response to different characteristics of data

A computing device includes a processor and a non-volatile dual in-line memory module (NVDIMM) connected to the processor. The NVDIMM includes a first memory having a first processing speed and a first storage capacity, a second memory having a second processing speed lower than the first processing speed and a second storage capacity larger than the first storage capacity, and a controller that evicts or fetches data between the first memory and the second memory. When the processor recognizes a first situation to evict data or a second situation to prefetch data, the processor transmits a command including first information of a logical address of data associated with the first situation or the second situation, second information of a length of the data associated with the first situation or the second situation, and third information indicating the first situation or the second situation to the NVDIMM.
