Method and device for persistent-memory mangement

摘要

The present invention relates to a method for managing memory space of a persistent-memory device and to a memory management device. The memory management method of the invention comprises a step of allocating (S 14 ) at least one first part of said memory space to a file system ( 74 ) upon request from said file system ( 74 ) or from an application ( 70 ). The method and the device of the present invention enable a dynamical allocation of persistent-memory space to a file system. This way, the memory space of a persistent memory is effectively used also for write-caching. At the same time, write-caching and storing steps can be accelerated.
