PROBLEM TO BE SOLVED: To provide a semiconductor memory in which the power consumption can be reduced and of which manufacture is easy. SOLUTION: This device is a semiconductor memory having a redundancy circuit RC replacing a defective memory cell by a redundancy memory cell in accordance with redundancy information, and provided with a charge pump 5 for programming redundancy information by dielectric-breaking down selectively a capacitor, and a redundancy control circuit 3 reproducing programmed redundancy circuit RC by supplying the prescribed electric charges to the capacitor and refreshing, and supplying reproduced redundancy information to the redundancy circuit RC.
