Memory data storage method of huge RFID (Radio Frequency Identification Device) label information

The invention discloses a memory data storage method of huge RFID (Radio Frequency Identification Device) label information, relating to the technical field of information processing. The method disclosed by the invention comprises the steps of: 1, dividing RFID label attribute information into three classes according to higher attribute updating frequency, high access frequency, low updating frequency, high access frequency, low updating frequency and low access frequency; 2, for the RFID label attribute information in each class, accessing RFID label attribute data one by one, sequentially storing the updated data in a cache block in batch; and 3, when the cache block is full or an updated RFID label attribute data set is met, writing contents in the cache block into the file. By using the method, the performance of access updating of the huge RFID label information is ensured and throughput between a memory and a disk during huge data exchange can also be ensured.
