摘要：
RFID tag circuits, tags, and methods are provided for using alternative memory lock bits. A pointer in tag memory is configured to point to one or the other of the alternative lock bits associated with a section of the memory for performing a function in response to a reader command. Upon receiving the reader command, the tag first checks the pointer and performs the function based on which lock bit(s) is selected.
