Abstract
RFID system components, such as readers and tags, communicate by transmitting and receiving a wave that conveys a bit stream. Informing signals, such as special bits, are inserted in the stream between words. An informing signal indicates whether a certain word is the last word in the stream or not.

-45. (canceled)
An integrated circuit (IC) for a Radio Frequency IDentification (RFID) tag that has an antenna arranged to receive a wireless wave, comprising:
- circuitry that is arranged to generate a stream of bits from the wave;
- a memory;
- and
- a processing block that is arranged to:
- (a) isolate a group of the bits from the stream,
- (b) designate at least one of the isolated bits as an informing signal,
- (c) designate the remaining bits of the group as a word,
- (d) append the word to a previously similarly designated word for forming a reception block, and
- (e) if the informing signal does not equal a preset termination return to (a), else terminate appending and perform an action that uses the reception block as one of an address for the memory and content for the memory.
