Title:
半導体集積回路装置及びそのプログラム方法
Document Type and Number:
Japanese Patent JP4282529
Kind Code:
B2
Abstract:
A semiconductor integrated circuit device includes a storage element, state sensing circuit, and control circuit. Information is programmed in the storage element by electrically irreversibly changing the element characteristics. The state sensing circuit is configured to sense the irreversibly changed state of the storage element in distinction from an unchanged state. The control circuit is configured to change the sensibility of the state sensing circuit.
