    Abstract: A memory system comprises a central processing unit. A memory management unit receives a virtual address from the central processing unit. The memory management unit converts the virtual address into a physical address. A main memory is assessed based on the physical address. The main memory stores data used the central processing unit. The main memory includes a first area including a non-volatile memory. First file data having a first characteristic is included in the first area of the main memory. The main memory includes a second area including a volatile memory. Second file data having a second characteristic different from the first characteristic is included in the second area of the main memory. A management table manages only the first area of the first and second areas of the main memory.

    Abstract: The present disclosure provides methods and apparatuses for data loss prevention of a storage device. In some embodiments, the data loss preventing method includes receiving, from a host system, a query plan corresponding to necessary data to be stored in a volatile memory. The data loss preventing method further includes generating, based on the query plan, a data priority list corresponding to the necessary data. The data loss preventing method further includes selecting, based on the data priority list, at least one portion of the volatile memory, when a main power supplied by the host system drops to or below a power level threshold. The data loss preventing method further includes moving the necessary data to the at least one portion of the volatile memory.

    Abstract: A computational storage device includes a control module, and a nonvolatile memory connected to the control module. The nonvolatile memory is configured to store a plurality of graph data elements, which comprises a plurality of nodes and a plurality of edges that connect at least a portion of the plurality of nodes to each other, in a first memory area and a second memory area each having a plurality of blocks and having different read speeds. The control module is configured to store a first graph data element of the plurality of graph data elements having a relatively high degree of association with one node of the plurality of nodes in the first memory area, and store a second graph data element of the plurality of graph data elements having a relatively low degree of association with the one node of the plurality of nodes in the second memory area.
