ABSTRACT:
A current source for powering programmable arrays which provides means of eliminating the current supplied to portions of the array which are unimportant to the boolean arithmetic equation which the programmable array is programmed to model. The circuit includes fusible links (33-1 through 33-M) between the current source and portions of the circuit which may be unnecessary. Also included is means of opening (13-1 through 13-M) the fusible links (33-1 through 33-M) which connect the current source with the elements of the programmable array which may be unnecessary, thereby saving the power used to generate the current which would have been wasted in driving the unnecessary portions of the programmable array.
