APPARATUS AND METHOD FOR MANAGING USER MEMORY OF RFID TAG
First Claim
1. An apparatus for managing a user memory of an RFID tag, the apparatus comprising:
- a memory usage information storing unit that stores memory usage information, the memory usage information comprising information regarding data stored in the user memory and information regarding a region of the user memory storing the data;
a memory registration-management unit that searches information regarding an empty region of the user memory by the memory usage information storing unit, provides the searched information to the specific application system, receives memory usage information regarding the specific data that is to be stored in the user memory from the specific application system, and stores and manages the memory usage information regarding the specific data in the memory usage information storing unit, if the specific application system requests the user memory to store specific data; and
a memory referring unit that provides the memory usage information regarding the specific data, which is stored in the memory usage information storing unit, to the application system that requests to refer to the specific data if referring to the specific data is requested.

Abstract
The present invention relates to a device and method for managing a memory of an RFID tag. The present invention provides an apparatus for managing a user memory of an RFID tag. The apparatus includes a memory usage information storing unit, a memory registration-management unit, and a memory referring unit. The memory usage information storing unit stores memory usage information. The memory registration-management unit searches information regarding an empty region of the user memory by the memory usage information storing unit, provides the searched information to the specific application system, receives memory usage information regarding the specific data that is to be stored in the user memory from the specific application system, and stores and manages the memory usage information regarding the specific data in the memory usage information storing unit, if the specific application system requests the user memory to store specific data. The memory referring unit provides memory usage information regarding the specific data, which is stored in the memory usage information storing unit, to the application system that requests to refer to the specific data if referring to the specific data is requested. According to the present invention, it is possible to systematically and efficiently manage data that is stored in the user memory region of the RFID tag by a plurality of users, and to prevent the storage positions of a plurality of data that are stored in the user memory region of the RFID tag from overlapping. As a result, it is possible to prevent a loss of data to be stored in the user memory region of the RFID tag.
