Patent ID: 6922134

Claim:
An RF transponder comprising an EEPROM memory, characterized by: a trimming bits portion of the EEPROM memory comprising at least one trimming bit; and at least one trimming bit circuit associated with the at least one trimming bit, wherein each one of the at least one trimming bit circuits comprises: a trimming EEPROM cell comprising a pair of EEPROM transistors, wherein the pair of EEPROM transistors comprises a first EEPROM transistor and a second EEPROM transistor which cooperate to represent a single bit of trimming information; a trim sensing circuit; a reference voltage line connected to the pair of EEPROM transistors; at least one sensing line connecting the trimming EEPROM cell to the trim sensing circuit; and a trimming line for outputting the single bit of trimming information from the trim sensing circuit.
