    Abstract: In one aspect, data is stored in a solid state memory which includes first and second memory layers. A first assessment is executed to determine whether received data is hot data or cold data. Received data which is assessed as hot data during the first assessment is stored in the first memory layer, and received data which is first assessed as cold data during the first assessment is stored in the second memory layer. Further, a second assessment is executed to determine whether the data stored in the first memory layer is hot data or cold data. Data which is then assessed as cold data during the second assessment is migrated from the first memory layer to the second memory layer.

    CPC classification number: G06F11/1096

    Abstract: In a method of operating the memory system, the method includes detecting whether data of a read-out unit read from a first cell region has an error correction code (ECC) failure, in response to an external read-out request for the read-out unit, recovering and outputting the data of the read-out unit by performing Redundant Array of Inexpensive Disk (RAID) recovery by using data and RAID parity read from other cell regions, recovering a plurality of pieces of data stored in the first cell region by performing the RAID recovery using the data and RAID parity read from the other cell regions, and migrating the recovered plurality of pieces of data to a second cell region in units of cell regions.

    Abstract: A memory access control method that can prevent a cell hammer phenomenon includes setting at least a part of all the memory cells a safe memory region, and setting the remaining memory cells to a normal memory region. In the safe memory region, some cells set to an enabled state are accessible for data writing or reading, and the remaining cells set to a disabled state are inaccessible. Based on a safe address mapping algorithm, access to all memory cells in the safe memory region is controlled such that access to the enabled memory cells is allowed and access to the disabled memory cells is prevented. The enabled memory cells in the safe memory region are spaced apart from each other by at least one disabled memory cell in a horizontal and/or vertical direction.
