Semiconductor apparatus with self-security function

摘要

A semiconductor apparatus includes a functional block that performs necessary functions for the proper operation; a functional signal line that is connected to the functional block to transmit a functional signal; and an enable signal line to supply an enable signal to the functional block. The enable signal line includes a part that is formed on an upper layer of the functional signal line and a resistor (33) connected to the enable signal layer, wherein the resistor causes the functional block to be disabled when the enable signal layer is broken.
