Method and system for controlling multiple electrical fuses with one program device
Abstract:
A fuse circuit comprising one or more one-time programmable electrical fuses; one or more unidirectional conductive devices each coupled to one of the fuses; a programming device coupled to the unidirectional conductive devices; and a selection module coupled to the electrical fuses for selecting a predetermined electrical fuse, wherein upon a selection by the selection module, a programming current is introduced through at least one selected electrical fuse, wherein the selection module is an N-to-one multiplexer selecting one of the N number of electrical fuses to be programmed, and the unidirectional conductive devices not coupled to the selected electrical fuse to prevent the programming current from interfering with the remaining electrical fuses.
