Abstract: A storage controller includes a co-access pattern mining unit configured to detect co-access patterns of data co-accessed during a particular time duration and to generate co-access groups including a plurality of pieces of data complying with the co-access patterns. The storage controller further include a co-access group matching unit configured to select a co-access group matched with read-requested data, among the generated co-access groups, and a data placement unit configured to store the data included in the selected co-access group in a pre-fetch buffer.

Abstract: A method of controlling a storage device and a random access memory includes, when a size of write-requested data is greater than a threshold, writing the write-requested data in the storage device and writing an address of the storage device in which the write-requested data is written in the random access memory. When the size of the write-requested data is smaller than or equal to the threshold, the write-requested data is written in the random access memory. The threshold is correlated to a size greater than a size of an area allocated to store the address in the random access memory.

Abstract: A cache management apparatus includes an access pattern analysis unit configured to analyze an access pattern of each of one or more pages present in a first cache by monitoring data input/output (I/O) requests, a page class management unit configured to determine a class of each of the pages based on results of the analysis performed by the access pattern analysis unit, and a page transfer management unit configured to transfer one or more pages classified into a first class including pages to be transferred, to a second cache based on results of the determination performed by the page class management unit.
