Patent ID: 8717052

Claim:
An integrated circuit device packaged in a semiconductor device package, the integrated circuit device comprising: one or more external terminals configured to receive mode selection signals selecting between a test mode and a normal mode of operation for the device; one or more external terminals configured in the test mode to receive fuse configuration data from an external source; a latch array including a plurality of latches each of which being configured in the test mode to receive a corresponding data portion of the fuse configuration data and to output a respective soft-blow signal based on the received data portion; and a fuse array circuit including a plurality of fuses and generating a respective output signal for each fuse based on whether that fuse is blown or not, wherein each latch in the latch array corresponds to a respective fuse in the fuse array circuits, and in the test mode the fuse array circuit receives the respective soft-blow signal from each latch and generates the respective output signal for that fuse based on the received soft-blow signal.
