Abstract
A blocking section is inserted between the control section and the fuse section of a fuse control logic circuit. The blocking section comprises switching means which block the flow of DC current during a power-up sequence and thus avoids the collapse of the power supply voltage with the attending potential for incorrect addressing and improper function and timing options. The insertion of the blocking section further eliminates indeterminate logic states when fusible means are not fully blown thus assuring correct voltage levels at the output of the circuit.
