AN RFID TAG WITH AN IMPROVED COMMUNICATION BETWEEN AN EXTERNAL LOGIC ELEMENT CONDUCTIVELY CONNECTED THERETO AND AN INTERROGATOR AS WELL AS A METHOD FOR SUCH COMMUNICATION

摘要

A memory access arbiter (MAA) in an RFID tag is connected to an unique address space (UAS), which comprises a non-volatile memory (NVM), a transferred data memory (TDM) and a status-information memory (SIM) storing information on the status of the transferred data memory (TDM). The transferred data memory (TDM) and the status-information memory (SIM) are volatile memories, e.g. of the RAM type having a memory capacity of 16 bits or 32 bits according to the standard of an applied RFID communication. The RFID tag of the invention provides for a faster communication between an interrogator and an external logic element by one order of magnitude, which is due to fast volatile memories for transferred data as well as for corresponding status information. A still higher communication rate is achieved by introducing a command that has not yet been standardized.
