1. In a semiconductor circuitry, having the number of available I/O (input/output) channels selected by bond-pad connections, circuitry for changing the initial selected number of I/O channels comprising: at least one bond-option circuit coupled to a voltage potential and having an enable/disable input, and an output signal coupled to I/O channel selection bond-pad; at least one latch fuse circuit coupled to a voltage potential and having an enable/disable input, and an output signal connected to said I/O channel selection bond-pad; said at least one latch fuse circuit further connected to receive an enable signal when said at least one bond-option circuit receives a disable signal, and to receive a disable signal when said at least one bond-option circuit receives and enable signal; and an enable latch fuse circuit for providing one of said enable and disable inputs when said fuse is not blown, and the other one of said enable and disable inputs when said fuse is blown.
