In the data write operation, the cell power supply line is forced into a floating state according to the bit line potential on a selected column and has the voltage level changed, and a latching capability of a selected memory cell is reduced to write data fast. Even with a low power supply voltage, a static semiconductor memory device that can stably perform write and read of data is implemented.

    摘要: The present invention provides a semiconductor device realizing reliable cutting of a fuse without enlarging layout area of a fuse element and the reduced number of wiring layers of a preventing wall that prevents diffusion of fuse copper atoms. A fuse is formed by using a wire in a metal wiring layer as an upper layer in a plurality of metal wiring layers. Wires are disposed just above and just below a fuse each with a gap of at least two wiring layers. In an upper layer, a power wire that transmits power supply voltage is used as a part covering a preventing wall structure just above the fuse.

    摘要: Provided is a semiconductor device having an electric fuse structure which receives the supply of an electric current to be permitted to be cut without damaging portions around the fuse. An electric fuse is electrically connected between an electronic circuit and a redundant circuit as a spare of the electronic circuit. After these circuits are sealed with a resin, the fuse can be cut by receiving the supply of an electric current from the outside. The electric fuse is formed in a fine layer, and is made of a main wiring and a barrier film. The linear expansion coefficient of each of the main wiring and the barrier film is larger than that of each of the insulator layers. The melting point of each of the main wiring and the barrier film is lower than that of each of the insulator layers.
