<p>Disclosed are a semiconductor device, a chip and a method for modifying bit data, which relate to the technical field of chip design, and add a modification manner for modifying bit data recorded in a chip. The chip for recording bit data of the present application comprises N columns of metal layers, and each column comprises M metal layers, N and M being integers not smaller than 2. A bitline of an NMOS transistor for recording the bit data is cured in a bottom or top metal layer of an edge column in the N columns of metal layers, and a drain of the NMOS transistor is cured in a bottom or top metal layer of another edge column. Adjacent metal layers in the same layer are in a state of being connected or disconnected, and a connection layer is or is not disposed between adjacent layers at the same column, so that a path exists or does not exist between the bitline and the drain. By adopting the solution, a modification manner for modifying bit data recorded in a chip can be added.</p> |
