Abstract
A semiconductor device is configured to prevent misprogramming of fuse circuits therein. The semiconductor device includes the following elements. A group of fuse element circuitsis configured to store a first data defining the circuit configuration. A fuse element circuitis configured to store a second data representing inhibition of programming the group of fuse element circuits. A control logic circuitis configured to program the first and the second data on the fuse element circuits. An AND gate circuitis configured to inhibit the control logic circuitfrom programming the group of fuse element circuitson condition that the fuse element circuithas been programmed.
