Chunfeng Li · Computer Technology and Development · 2010
In order for smart cards within the limited storage space for effective allocation and management to meet the practical needs of the USIM card file system,research of dynamic storage management is essential.In this paper,NOR Flash has a write endurance limit,written after the first cleaning features and USIM card storage space allocation for multi-application features,the use of static and dynamic combination of theory,design a hybrid storage organizing data storage,and gives a dynamic storage management methods and specific description of the algorithm.Test results confirmed that the method is suitable for 3G USIM card multi-application requirements,to ensure the reliability of the smart card file system to improve the utilization of Flash,maximizing the life of the extension of Flash,effectively improve the speed of data retrieval.
