DATA STREAMING APPARATUS FOR RADIO FREQUENCY IDENTIFICATION TAG
First Claim
Patent Images
1. A data streaming apparatus applied to a memory administration means of a tag for radio frequency identification communication, the apparatus comprising:
- a memory unit including a plurality of unit banks capable of switching between active and inactive states, one or more unit banks sequentially storing one or more pieces of streaming data; and
a memory administration unit receiving information on an initial address or a data size or identification information corresponding to the initial address or the data size and obtaining and providing data by selectively activating only the unit bank corresponding to a current address while incrementing the current address until the amount of data obtained by incrementing the address starting from the initial address reaches the data size.

Abstract
The invention relates to a data streaming apparatus for an RFID tag capable of streaming large scale data with low power consumption without a complicated structure. A mass storage is segmented into unit banks, and only the unit banks are selectively operated in a sequential manner. As a result, a tag capable of streaming large scale data with low power consumption can be provided.

10. A data streaming apparatus for a radio frequency identification (RFID) tag, the apparatus comprising:
-
a wireless communication unit exchanging data with an external reader device; a modulation/demodulation unit transmitting/receiving data to/from via wireless communication unit; a memory unit having a plurality of unit banks capable of switching between active and inactive states, one or more pieces of the streaming data being sequentially stored in one or more unit banks; a control unit outputting information for requesting the streaming data stored in the memory unit in response to a streaming data request received via the modulation/demodulation unit and receiving the streaming data accordingly to provide it to the modulation/demodulation unit; and a memory administration unit obtaining data and provide it to the control unit while sequentially activating necessary unit banks in the memory unit based on the information for requesting the streaming data from the control unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
