RFID tags with electronic fuses for storing component configuration data
First Claim
Patent Images
1. An RFID tag circuit comprising:
- a fuse adapted to store configuration data in a way that survives loss of power;
an operational component adapted to operate based on the configuration data; and
a non-volatile memory (NVM) memory array distinct from the fuse and having a plurality of NVM cells that are addressable in terms of a row and a column and are adapted to store data in a way that survives loss of power.

Abstract
An RFID tag has a fuse that is adapted to store configuration data in a way that survives loss of power. The fuse can be one time programmable or many times programmable, and be implemented with a non-volatile memory. The configuration data becomes available to an operational component of the tag, such as at power up, controlling its performance.

72. A device comprising:
-
means for inputting from a tag fuse programmed configuration data that is stored in the fuse in a way that survives loss of power, the fuse being distinct from a tag non-volatile memory (NVM) array that has a plurality of NVM cells that are addressable in terms of a row and a column and are adapted to store data in a way that survives loss of power; and
means for operating a tag operational component distinct from the tag fuse as controlled by the input configuration data. - View Dependent Claims (73, 74, 75, 76, 77)
