Abstract
A circuit arrangement, particularly for electronically processing and/or storing digital signals, the circuit arrangement comprising at least one programmable switching device (referred to as “fuse”) for permanently switching off predetermined parts of the circuit arrangement, at least one of the fuses having a multistage structure. This provides a measure allowing both a versatile and modifiable prototype construction and a possibly simple and reliable production of the corresponding derivatives.
Claims3
A circuit arrangement, particularly for electronically processing and/or storing digital signals, the circuit arrangement comprising at least one programmable switching device (referred to as “fuse”) for permanently switching off predetermined parts of the circuit arrangement, at least one of the fuses having a multistage structure.
A microprocessor, characterized by a circuit arrangement, particularly for electronically processing and/or storing digital signals, the circuit arrangement comprising at least one programmable switching device (referred to as “fuse”) for permanently switching off predetermined parts of the circuit arrangement, at least one of the fuses having a multistage structure.
A microprocessor for use in a chip card (referred to as “smart card controller”), characterized by a circuit arrangement, particularly for electronically processing and/or storing digital signals, the circuit arrangement comprising at least one programmable switching device (referred to as “fuse”) for permanently switching off predetermined parts of the circuit arrangement, at least one of the fuses having a multistage structure.
