DATA MANAGING METHOD OF SYSTEM HAVING NONVOLATILE MEMORY CAPABLE OF STORING PERSISTENT DATA

摘要

PURPOSE: A method for managing data in a system storing perpetuation data in a nonvolatile memory is provided to increase the space efficiency of the nonvolatile memory and to reduce overheads caused by unmarshaling and marshaling operation by storing and managing a data structure used in an application as the perpetuation data without changing the structure into a file. CONSTITUTION: A root object of application data and a sub object to which the root object referrers are stored in the nonvolatile memory(10). The root object includes a pointer referring to the sub object. Virtual addresses of the root object and the sub object are mapped with a physical address of the nonvolatile memory by page units. The application data includes first application data executed by a first process and second application data executed by a second process. [Reference numerals] (10) Receiving application data; (100) Storing a root object and a sub object of the application data in an NVRAM, wherein the root object stored in the NVRAM includes a pointer that refers to the sub object stored in the NVRAM;
