ABSTRACT:
A programmable read-only memory (PROM) circuit is provided wherein each one of a plurality of fusible links is coupled between a different row and column conductor of a matrix of row and column conductors and wherein each one of the row conductors is coupled to a corresponding one of a plurality of row driver circuits, each one having an output transistor connected to the corresponding one of the row conductors. Switch means are provided for feeding a first level of base current to the output transistors during the programming mode and for feeding a second, lower level of base current to such output transistors during the read mode.
