摘要： 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.

摘要： Provided is a system storing data received from an application or file system in a non-volatile memory system of single-level cells and multi-level cells in accordance with one or more data characteristics. The non-volatile memory system includes a non-volatile memory cell array having a plurality of multi-level cells forming a MLC area and a plurality of single-level cells forming a SLC area, and an interface unit analyzing a characteristic of the write data and generating a corresponding data characteristic signal. A flash transition layer receives the data characteristic signal, and determines whether the write data should be stored in the MLC area or the SLC area based on whether or not the write data will be accessed by the file, or whether the address associated with the write data is frequently updated or not.
