Method and device for persistent-memory mangement

A file system device, comprising a file allocation unit adapted to maintain a file allocation table at a current status, said file allocation table assigning at least one disk space address to at least one file, wherein said file allocation unit is adapted to communicate with a memory management device that is related to a persistent-memory device and to include an address of at least one first memory space of said persistent-memory device in the maintenance of said file allocation table.

An application device, comprising a persistent-memory device connected to a processor, and a data management unit adapted to manipulate data in said persistent memory device, wherein said data management unit is adapted to write at least one third executable file to said persistent memory device, or to provide the file system with a reference to at least on third executable file in said file system, such that by executing said third executable file said processor is adapted to transform said data into a predetermined data-sequence form.

A data processing system, comprising a memory management device for managing a memory space of at least one persistent-memory device, comprising a memory allocation unit adapted to communicate with at least one application device and to allocate at least one first part of said memory space to said application device, wherein said allocation unit is further adapted to communicate with at least one file system device, and to allocate on request from said application device or from said file system device said first part of said memory space to said file system.

A method for managing memory space of a persistent-memory device, comprising a step of allocating at least one first part of said memory space to a file system device upon request from said file system device or from an application device.
