Circuit and method for a circuit of selecting reference voltage
Different reference voltages are employed in different logical electrical circuits. In the conventional arts, a reference voltage circuit is only employed in a specific logical electrical circuit or a reference voltage circuit with fuse can changes a reference voltage by fusing the fuse. Nevertheless, the reference voltage circuit with fuse is still only employed in a specific system of logical circuit regardless of the fuse is fused or unfused. A select reference voltage circuit for a logical electrical system of the present invention can solve the problem. Therefore, the select reference voltage method for a logical electrical system can be employed in different systems having respective different system voltages.
