Abstract:
An electrical fuse determination circuit that can speedily and reliably incorporate an electrical fuse data and improve a reliability of electrical fuse device, includes a first electrical fuse device of which one end connects with a higher voltage, a second electrical fuse device of which one end connects with a lower voltage, a set portion that puts one of the first electrical fuse device and the second electrical fuse device in a conductive state, and a determination portion that determines a voltage level of a predetermined contact point connecting the other end of the first electrical fuse device and the other end of the second electrical fuse device.
