Abstract
The disclosure relates to an integrated circuit for a radio-frequency identification (RFID) tag. Example embodiments include an integrated circuit (101) for an RFID tag, the integrated circuit (101) comprising: a memory (104) for storing data; a transceiver (107) for receiving signals from, and transmitting signals to, an antenna (102); and a controller (103) configured to process signals received via the transceiver (107) and to access data stored in the memory (104); wherein upon receiving, via the transceiver module (107), a lock command referring to a data block in the memory (104), the controller (103) is configured to generate error correction data for the data block and to store the error correction data in the memory.
Claims10
An integrated circuit for an RFID tag, the integrated circuit comprising:
- a memory for storing data;
- a transceiver for receiving signals from, and transmitting signals to, an antenna;
- and
- a controller configured to process signals received via the transceiver and to access data stored in the memory,
- wherein upon receiving, via the transceiver module, a lock command referring to a data block in the memory, the controller is configured to generate error correction data for the data block and to store the error correction data in the memory, and
- wherein the controller is configured to operate in an error correction mode associated with the data block in the memory, wherein when the error correction mode is activated the controller is configured to:
- perform an error check on the data block by comparing the data block to error correction data associated with the data block;
- and
- if the error check determines that the data block comprises an error, correct the data block using the error correction data.
A method of correcting errors in a memory of an RFID tag, the method comprising:
- receiving, at an antenna of the RFID tag, a lock command referring to a data block stored in the memory of the RFID tag;
- in response to receiving the lock command, generating error correction data for the data block and storing the error correction data in the memory;
- and
- during an error correction mode associated with the data block in the memory:
- performing an error check on the data block by comparing the data block to the error correction data associated with the data block, and
- if the error check determines that the data block comprises an error, correcting the data block using the error correction data.
