ABSTRACT:
A circuit for storing information by blown and unblown fuses has at least two fuses per bit and an information output circuit. The information output circuit discriminates between the state in which all the fuses are unblown and the state in which at least one of the fuses is blown, and provides an output in accordance with the result of the discrimination as stored information.
