An information processing device includes a memory array and a controller. The memory array includes a data field that stores file data and a management information field that stores information regarding the data field. The controller controls a writing operation to the memory array. The controller stores a portion of the file data, corresponding to a product of a positive-integer and a predetermined unit block size, in the data field by block units, with reference to the data field information of the management information field.

Information processing device having data field and operation methods of the same

Disclosed is a semiconductor memory system and wear-leveling method thereof. The semiconductor memory system is comprised of a nonvolatile memory including a plurality of logic blocks each of which is divided into a plurality of entries, a file system detecting a type of data to be stored and allocating the logic block or the entry for storing the data in accordance with the data type, and a translation layer leveling wearing degrees over the logic blocks or the entries in accordance with the data type.

Semiconductor memory system and wear-leveling method thereof

A data management method of a non-volatile memory device includes writing data and representing a state of the data. The state includes one of multiple possible states. A state of the multiple possible states corresponding to a final operation is determined as a valid state of the data.
